Answer:
The correct answer is - intermediate care facility.
Explanation:
Intermediate care facilities are the care units that provide health services or health care to the patients who require care and services due to their mental and physical condition, which is supervised by physicians and nurse however they do not need, skilled nursing staff.
It is called intermediate care because it is the care between intensive and basic care where at least a registered nurse is supervising the patient.
Thus, the correct answer is - intermediate care facility.
One of the known effects of acid rain is that it leaches calcium carbonate out of the soil. A study in a region that received significant amounts of acid rain showed that birds were laying eggs with highly porous shells. As a result, the bird population was declining. What is the MOST LIKELY cause of the observed quality of egg shells? A) Acid rain leaches out the calcium that is the most significant component of egg shells. B) The birds are unable to get calcium from the soil because the calcium has been leached out by the acid rain. C) The birds are unable to get calcium from the soil because the calcium has been consumed by the snails to secrete their shells. D) Calcium deficiency was caused because snails in the birds’ diets are unable to get enough calcium to secrete their shells.
Answer:
B) The birds are unable to get calcium from the soil because the calcium has been leached out by the acid rain
Explanation;
Calcium is needed by birds in large quantities for the development off the egg shell production and for healthy growth of newborn chicksCalcium cannot be stored in the skeleton of the birds since it would make them too heavy and can easily be attacked by predators.Therefore the birds have to get calcium directly from its source and eat it. Lack of calcium in the soil lead to lack of a source of calcium for the birds thus their eggs might end up failing to hatch due to the small holes on its shell and once there is air in the egg shell no hatching can take place leading to decline in population.

How does biodiversity support healthy ecosystems
ANSWER: Biological biodiversity refers to all the different kinds of life that are obtainable in a particular ecosystem, this include all the plants and animal populations that are found in a particular geographical area.
Biodiversity supports healthy ecosystem because it enhances the productivity and the survival of the ecosystem. For instance, in a situation where there are large number of different plant population in an ecosystem, such population will present variability in genetic make up. If a negative event occur in the ecosystem, it will be possible for some plants to survive. But, in a situation where it is only one type of plant that is obtainable in the ecosystem, it will be quite easy to wipe all of them out at once. For instance, a disease outbreak can easily destroy all the plants.
What are the conditions required to maintain allele frequency in a population?
Answer:
A large population No change in allelic frequency due to evolutionary mechanisms (mutation, natural selection, gene flow, genetic drift)Random matingExplanation:
According to Hardy-Weinberg Law, allele frequencies of the population will remain constant through the generation if a population is large, without evolutionary mechanisms acting on it (mutation, natural selection, gene flow, genetic drift), if mating is random. In other words, population is equilibrium (Hardy-Weinberg equilibrium).
Allele frequency describes how often an allele appears in a population. This measure is usually expressed in percentage. Allele frequency can describe the variation that exist within the population. It can be calculated as the number of alleles divided with the total number of gene copies in that population.
Change in allele frequencies over a certain short period of time is defined as microevolution. Mechanisms of evolution that can change allele frequencies through time are mutations, natural selection, genetic drift and gene flow (migrations).

Population [tex]= 300[/tex]
Net growth in population in the next year [tex]= 12[/tex] %
New population [tex]=[/tex] Existing population + (Net growth in population [tex]*[/tex]Existing Population
Substituting the given values in above equation, we get -
New population[tex]= 300 + ( \frac{12}{100} *300)\\= 300 + 36\\= 336\\[/tex]
Hence, there are total [tex]336[/tex] butter flies.
Where does the energy for human metabolism come from
Answer:
From food
Explanation:
Food energy is a chemical energy used by humans through the process of cellular respiration. Food contain macromolecules such as lipids, proteins, carbohydrates, water, vitamins, and minerals that are necessary for the human metabolism and they are broken down and used by the series of metabolic steps (glycolysis, Krebs cycle, electront transport chain and oxidative phosphorilation). Digested macromolecules should be used either as a source of energy or as building blocks for the cell.
At the end of catabolic processes within an organism food energy is transformed into energy usable by the cell-ATP.

14. In what type of cell would meiosis occur? A. Lung cell B. Brain cell C. Blood cell D. Sex cell
Answer:
I believe it is a sex cell.
Explanation:
The meiosis process occurs in gametes or sex cells. Therefore, option D is correct.
Meiosis is a specialized type of cell division that occurs in organisms that reproduce sexually. It involves the division of a diploid (2n) cell into four haploid (n) cells, resulting in the production of gametes (sex cells) such as sperm and eggs.
Meiosis consists of two successive divisions, known as meiosis I and meiosis II. The process is characterized by specific stages, including prophase I, metaphase I, anaphase I, telophase I, and cytokinesis, followed by prophase II, metaphase II, anaphase II, telophase II, and cytokinesis.

A virus cannot reproduce on its own. Viral DNA or RNA must enter the host cell and direct the cell to make the materials needed to produce more viral particles. There are two pathways a virus may take: the lytic or lysogenic pathway.
How are the lytic and lysogenic viral pathways ALIKE?
A) They both have a prolonged period of dormancy.
B) They both eventually cause the death of the host cell.
C) In both cases, viral DNA is replicated when the host cell undergoes fission.
D) In both cases, viral DNA is integrated into the host DNA for a period of time.
In both cases, viral DNA is integrated into the host DNA for a period of time
Answer:
B) They both eventually cause death of the host.
Explanation:
Viruses do not have their own energy producing system. Thus, viruses can only reproduce or replicate using host energy and reproduce by two methods. These are called the lytic cycle and the lysogenic cycle. In both the cycles, the viruses inject their genetic material into the host cell. In the lysogenic cycle, the viral DNA is integrated into the host DNA, while in the lytic cycle, the viral DNA exists as a separate free floating molecule within the host cell, and it reproduces separately from the host DNA. In both the cases the host cell die.

Carbon that gets into the soil through (animal death or defecation) can get buried and eventually (after a really long time) turn into what?
A. Algae
B. Water
C. Bacteria
D. Fossil Fuels
Answer:
D
Explanation:
Crude oils, shale, and natural gas are some of the fossil fuels formed in this way. They are specially formed when vast amounts of algae die and sink to the bottom of the oceans over time and accumulate with sediments. They become buried under vast layers of sediments that apply high pressure. Over time, the high pressure and temperature turn the organic molecules into fossil fuels.

The net result of a single glycolysis run is the formation of
Answer:
2 pyruvates, 2 ATP, 2 NADH
Explanation:
Glycolysis is the process in which glucose is broken down to pyruvate in order to produce energy. It occurs in cytosol and it can be divided into two phases: phase that requires energy (two ATP molecules are used) and phase that produces energy (four ATP molecules together with two NADH are produced).
After the glycolysis, which is the first step in cellular respiration, final products (two pyruvats) are further used. The next steps are: pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation.
which process occurs repeatedly after zygote formation to increase the number of cells
Answer:
Mitosis
Explanation:
A zygote is formed after the fertilization of the egg by sperm. The zygote then undergoes rapid cell division by mitosis to form a morula, blastula, gastrula and then an embryo. In mitosis, the cell replicates its genetic material and organelles and then splits into two identical cells. Mitosis is required for growth and development.
This is formed as a waste product in photosynthesis and used as a reactant in respiration.
Answer:
Oxygen
Explanation:
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.

Answer:
Overall DeltaG = -6.40 kJ/mol
Delta G = 31.6 - 6.4 =25.2 KJ
T = 17 + 273.15 =290.15 K
Delta G = -RT * Ln (K)
25.2 * 10^3 J = -(8.314 J/moles*k)(290.15K) * Ln (K)
So (Delta G)/(-RT) = Ln (K)
Ln K = -10.44643114
Thus k = 2.905 *10^-5
Answer:
Luciferase is an enzyme that belongs to the oxidative enzyme set of some bioluminescence reactions. This phenomenon was discovered by Rafaël Dubois, who detected the emission of light in some living things was nothing more than an enzymatic oxidation, in which luciferase was the catalyst, and luciferin the substrate. This phenomenon was frequently detected in fireflies and in the Pholas dactylus mollusk, and later in Cnidarians (Renilla reniformis), marine copepods (Gaussia princeps), abyssal molluscs (Oplophorus gracilirostris), bacteria, etc.
Explanation:
The biological role of luciferase lies in its quality as a catalyst for some types of bioluminescence. Bioluminescence is a type of chemiluminescence, it consists of the oxidation of luciferin, a luminescent substance, catalyzed by luciferase. Said reaction begins with luciferin whose carboxylic group reacts with the phosphate group of ATP, forming luciferyl adenylate. This molecule is oxidized (a process catalyzed by luciferase), resulting in an intermediate peroxide (luciferase-luciferin-AMP-O2 complex) which, upon releasing a molecule of carbon dioxide, results in a ketoderivative, the oxyluciferin, which is excited, returning to its normal state by releasing a photon of light:
Luciferin + O2 → Peroxidic intermediary (luciferase-luciferin-AMP-O2 complex) → [oxyluciferin] → oxyluciferin → light
How does pH affect enzyme activity? Use the enzymes pepsin and trypsin as examples.
Answer:
The change in PH not only effect the shape of enzymes, but it may also change properties the of substrate so that that substrate cannot control to bind the active site and it cannot undergo catalysis.
In general enzymes have a PH optimum. However this optimum is not same for each enzyme.
Explanation:
For Example; The enzyme pepsin is most active at an acidic PH, Whereas the enzyme trypsin performs best at slightly alkaline PH. the increase or decrease in PH can change the concentration of ion in a solution
The majority of triglyceride digestion occurs in the small intestine facilitated by the enzyme __________ ________.
Answer:
The correct answer is PANCREATIC LIPASE.
Explanation:
The three types of food eaten by man are broken down into three different components during digestion. Carbohydrate is broken down to glucose, fat and oil is broken down to fatty acid and glycerol and proteins are broken down to amino acids. Most of these digested products are absorbed at the small intestines.
The presences of triglycerides at the small intestines usually stimulates the secretion of pancreatic lipase enzyme and bile. The bile break down the fat molecule and increase its surface area so that pancreatic lipase will be able to work on it effectively. Thus, triglyceride digestion at the small intestines is facilitated by the enzyme pancreatic lipase.
Triglyceride digestion primarily occurs in the small intestine facilitated by the enzyme pancreatic lipase which breaks them down into two free fatty acids and a monoglyceride. Bile salts also support this process by emulsifying the fats.
Explanation:The majority of triglyceride digestion happens in the small intestine with the aid of the enzyme called pancreatic lipase. This enzyme is produced by the pancreas and released when food arrives in the small intestine. It then breaks down the triglycerides into two free fatty acids and a monoglyceride, which includes both short-chain (less than 10 to 12 carbons) and long-chain fatty acids. Additionally, the bile salts emulsify the fats which further facilitates this digestive process. The digestion of triglycerides is an important part of lipid metabolism.

Suppose you observed 240 progeny that resulted from a monohybrid cross and involved genes that obeyed Mendelian inheritance, how many heterozygous progeny would you expect to observe?
Answer:
120
Explanation:
If there is a monohybrid cross that involved genes that obeyed Mendelian inheritance this means that parental generation includes two true breed parents (both homozygous but with different genotype).
If we name the gene with A:
P: AA x aa
F1: Aa Aa Aa Aa
F2: AA Aa Aa aa
Half of them will be heterozygous, it means 120.
A gene coding for __________ proteins is likely to be found in a genomic island of a pathogenic bacterial strain and not found in a nonpathogenic strain.
Answer: CAN I GET THE ANSWER CHOICES AND I MAY THINK ITS PATHOGENIC
Explanation:
A gene coding for virulence factors proteins is likely to be found in a genomic island of a pathogenic bacterial strain and not found in a nonpathogenic strain.
Genomic islands are clusters of genes that are present in some strains of a bacterial species but not others. These islands often contain genes that confer an adaptive advantage to the bacteria, such as antibiotic resistance, metabolic capabilities, or pathogenicity. In the context of pathogenic bacterial strains, genomic islands frequently carry genes that encode for virulence factors proteins that enable the bacteria to cause disease in a host organism.
Virulence factors can include a variety of proteins, such as adhesins, which help bacteria attach to host cells; toxins, which can damage host tissues; and enzymes that may help the bacteria evade the host's immune response. The presence of these genes in a pathogenic strain and their absence in a nonpathogenic strain suggests that they play a role in the ability of the pathogenic strain to cause disease.
Therefore, when comparing pathogenic and nonpathogenic strains of bacteria, one would expect to find genes coding for virulence factors in the genomic islands of the pathogenic strain, as these proteins contribute to its ability to infect and harm a host.

Despite the differences in mature plant cells, all of them are derived from meristem cells. The three major types of tissue systems develop from the meristem. Meristems develop cells in all but which tissue? A) notocord B) protoderm C) procambium D) ground meristem
Answer:
A) notocord
Explanation:
Answer:
Notochord
Explanation:
Meristem cells are a group of plant cells capable of division and growth that reside in zones where growth can occur. As undifferentiated cells, they are considered as stem cells in animals given that they are the origin of many of the cells that go on to rapidly differentiate/specialize and form various parts of plant. A collection of meristem cells performing a specific function is called meristem tissue.
Meristems are classified based on their location or position; apical meristem (at the tips), intercalary (in the middle) and lateral (at the sides). Apical meristem is further divided into:
- Protoderm (which differentiates into epidermis)
- Ground meristem ( differentiation gives rise to parenchyma, collenchyma and sclerenchyma)
- Procambium ( differentiation results in the production of vascular tissues of the plant; xylem and phloem)
Notochord is a cartilaginous skeletal rod supporting the body in all embryonic and some chordate animals. Notochords are only found in the phylum Chordata, a group of animals including humans. Hence, notochords is not a structural characteristics of plants and cannot be produced by the meristem cells in plants.
