Answer:
K-strategists
Explanation:
Reproductive pattern in organisms can be typically categorised into two:
1. K- Strategy
2. R- Strategy
K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.
R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.
Examples of K-strategists are elephants and man
Examples of R-stategists are grasses and microbes.

List the three functions of kidney
Most notably, kidneys remove dangerous toxins and excess water from your blood and eliminate them through your urine. Kidneys also perform other amazing physiological feats, from regulating the amount of fluid in your body to controlling the salt content of that fluid. Here are three more amazing kidney functions.
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.
3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

Final answer:
Learned behaviors are not inherited traits and are not passed from parents to their offspring. These behaviors are developed after birth, influenced by environmental factors and previous experiences, highlighting the adaptive nature of organisms.
Explanation:
The question asks whether learned behaviors are inherited traits, with the correct answer being that learned behaviors are not passed from parents to their offspring and are not inherited traits. Instead, learned behaviors are skills and responses that animals develop after birth, influenced by environmental changes and previous experiences.
This distinction is crucial in understanding the adaptive capabilities of organisms in response to their surroundings. Learned behaviors include imprinting, habituation, conditioning, and cognitive learning, enabling organisms to adapt to environmental changes. Unlike innate behaviors, which are instinctual and genetically programmed, learned behaviors can be modified and are not fixed.

When a light wave is absorbed by an object what happens to the absorbed light energy
Answer:
The frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.
Explanation:
Final answer:
Absorbed light energy is typically converted into heat or another form of energy by the object absorbing it. Objects appear colored due to the reflection of certain wavelengths, while those absorbed contribute to energy transformation within the object.
Explanation:
What Happens to Absorbed Light Energy
When a light wave is absorbed by an object, the absorbed light energy is converted into other forms of energy, typically heat. This transformation is a result of light interacting with matter. For instance, pigment molecules in plants absorb visible light for photosynthesis, while materials like glow-in-the-dark plastics can absorb light energy and later re-emit it as phosphorescence. The energy from light that's absorbed can also contribute to an object's temperature increase.
Moreover, the absorption of light depends on the wavelengths of light and the material it interacts with. Objects appear colored because they reflect certain wavelengths while absorbing others. For example, a red apple appears red because it reflects red wavelengths and absorbs others.

the special reproductive structures known as sperm and egg are correctly referred to as
Answer:
The correct answer is - gametes or sex cells.
Explanation:
Gametes are the sec cells that are produced by the gonad or reproductive gland or organs. Female gametes are called egg cells where as male gametes are known as sperm.
These gametes fuse to produce offspring of an individual. The process of fusing sex cells or gametes called fertlization.
Thus, the correct answer is - gametes or sex cells.
They are correctly referred to as Gametes
Gametes are reproductive cells formed during sexual reproduction towards producing a new organism which is termed zygote. Gametes in males and females bodies are different.
Further ExplanationHowever, the Male gamete is called sperm, and the female gamete is called egg or ovum. Usually, the male gamete is smaller than the female gamete. It also usually mobile. The male gamete has a long tail known as flagellum, which allows it to move towards the female gamete. On the other hand, the female gamete is always larger than the sperm and is not mobile unlike the male gametes.
Gametes can also be defined as identified sex cells which contain half the number of chromosomes of the parent. Fertilization takes place when a sperm and an egg connect, forming a single cell which is termed “zygote.” The zygote increases into an individual or more.
However, Humans have forty-six (46) chromosomes resulting from a twenty-three (23) pairs.
Formation
Gametes are formed by a process in which cells are divided into more parts called Meiosis. The division process results into four daughter cells which are called haploid. A set of chromosomes is usually located in Haploid Cells.
Fertilization is the connection of the male and female gametes which leads to zygote formation.

Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species.
Use what you have learned from the lesson, as well as reliable and reputable resources, to evaluate this claim.
The statement is a short one, but it manages to sum up what happens in nature in a simplified manner.
All the species have evolved to a certain type of environment, thus being perfectly well adapted to certain living conditions, and developing traits that are advantageous for the survival in that particular environment. But the Earth is constantly changing, and those changes result in changes of the environment, sometimes gradually, sometimes very quickly. The loss or change of environment always has huge impact on the species. Some go extinct, especially the ones that have been too specialized, while the more opportunistic and less specialized species often manage to survive. The ones that manage to survive face a new environment, so they evolve in a way that is advantageous for them to survive in the new environment, thus giving rise to new species. Other species may already have the required traits for the new environment but have been living in different area, so they will gradually move in this new environment as it suits them, thus having a situation where the ecosystems will eventually be totally changed and unrecognizable from the predeceasing ecosystems.
Answer:
Changes in environmental conditions like floods or forest fires, always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species. If humans are hunting for predators like jaguars, this would affect the food chain and cause a loss of biodiversity. The prey would survive and reproduce more because there would be fewer predators to eat them. Therefore, the population can increase. Species can also evolve to fit the environmental conditions. For example, if there is a major drought in an area, some organisms could adapt and evolve to the drought. However, the organisms that can't evolve would die and would also cause a loss of biodiversity. Environmental conditions like climate change affect many organisms. One pine tree species went extinct because of climate change. The seeds couldn't grow and reproduce in the weather, so the organism gradually went extinct.

Both pseudopods and flagella are used for movement. Pseudopods are temporary and used to engulf food, while flagella are hair-like structures used for locomotion in dinoflagellates.
Explanation:The question pertains to the comparison of pseudopods in sarcodina and flagella in dinoflagellates. The correct answer to the question is that both pseudopods and flagella are used for movement, but only pseudopods are used to engulf food. Pseudopods are temporary, foot-like extensions of the cytoplasm enabling sarcodina to move and capture prey. Conversely, flagella are long, hair-like structures that allow dinoflagellates to move through their aquatic environments. While flagella contribute to the locomotion of dinoflagellates, they are not involved in engulfing food.

How does studying the DNA of different types of organisms provide evidence that all life on earth is related?
All DNA of creatures is made from the same materials, and is largely the same. (Humans are less than 5% different than primates genetically)
Studying DNA of different species reveals that all life on Earth shares a common ancestor, due to universal genetic similarities. Genomics has enabled the construction of the 'tree of life' illustrating these relations. Molecular evidence, such as genome comparisons, helps us understand the evolutionary connections among diverse organisms.
Studying the DNA of different organisms provides evidence that all life on Earth is related because all extant life shares a common ancestor. This is visible in the fundamental similarities at the molecular level, such as the universal genetic code, the use of DNA to store genetic information, and the usage of similar molecular building blocks. Genomics and genetics have made it possible to construct the 'tree of life', a diagram illustrating the relationships among organisms by examining nucleic acid sequences that they have in common. This shows the deep connections across all living organisms, from the molecular level to larger structures and functions.
The genomes of various organisms show that they share a high degree of similarity in DNA sequences which code for proteins and other molecules. Through detailed analyses of these genetic codes, scientists have been able to determine homologies that imply a common ancestor. As evolution progressed, the genetic code established early in Earth's history evolved into the diverse life forms observed today. Additionally, molecular evidence of evolution, such as the comparison of genomes, sheds light on how evolution occurs and the relationships among species.

List two species that are clear examples of genetic drift and speciation events.
Answer:
Cougar and cheetah
Explanation:
The cougar and the cheetah are a nice example of genetic drift and speciation. These two felids have a common ancestor that lived in North America. As the environment was changing, some individuals of the species started to occupy the forests, especially in the mountainous regions, while other individuals moved into the open grasslands where there was an open niche in the food chain. The cougar emerged from the ones that lived in the mountainous forests, remaining typically cat like, with lot of muscle tone, relatively short legs, and being an ambush predator. The cheetah emerged from the ones that started living in the grasslands. Unlike their cousins, these individuals experienced lot of changes, developing long legs, larger heart and lung capacity, losing their retractable claws, and becoming sprinters. As the conditions changed, the cheetah migrated, eventually reaching Eurasia and Africa, while the cougar spread across most of North America and South America.
DNA Sequence 5'- AGT AAC GGC AGA CTT CTC CAC AGG AGT CAG GTG CAC CAT -3' mRNA Sequence: 5'- ........................................................-3' Nucleotides: ACGTU
Answer:
5'- UCA UUG CCG UCU GAA GAG GUG UCC UCA GUC CAC GUG GUA -3'
Explanation:
As we know there are four nitrogenous bases in DNA double helix, they are divided into two categories Purines and Pyrimidines.
Purines:
Adenine (A) and Guanine (G)
Pyrimidines:
Cytosine (C) and Thymine (T)
Note: In case of RNA Thymine will be replaced with Uracil (U)
During Transcription, A DNA sequence is copied into messenger RNA (mRNA). As a first step the double helix molecule of DNA will unwind and one of the strands will be used as template. RNA polymerase moves along the template strand and synthesize mRNA.
The complementary mRNA sequence to the given DNA sequence would be 5'- UCA UUG CCG UCU GAA GAG GUG UCC UCA GUC CAC GUG GUA -3'. This mRNA sequence is then decoded during the process of translation into a polypeptide chain with a specific sequence of amino acids.
Explanation:The DNA sequence provided is a template strand from which the complementary mRNA sequence is transcribed. The transcription process follows the principle of base pairing but uses uracil (U) in RNA instead of thymine (T) in DNA. Thereby, adenine (A) pairs with uracil (U), thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C) in the mRNA sequence.
So, the complementary mRNA sequence to the provided DNA sequence 5'- AGT AAC GGC AGA CTT CTC CAC AGG AGT CAG GTG CAC CAT -3' would be: 5'- UCA UUG CCG UCU GAA GAG GUG UCC UCA GUC CAC GUG GUA -3'.
This mRNA sequence then goes through a process called translation where it is decoded into a polypeptide chain (a protein) with a specific sequence of amino acids. The three-nucleotide sequences also known as codons in mRNA each correspond to a specific amino acid in the peptide chain.

What are the two main reasons archaea and bacteria belong to different domains
Archaea and bacteria are placed in different domains due to their distinct evolutionary histories and structural differences, specifically the composition of their cell walls and membranes.
Explanation:The two main reasons why archaea and bacteria belong to different domains are their distinct evolutionary histories and structural differences. Archaea and bacteria are both unicellular prokaryotic organisms, but they evolved separately from each other and hence have different genetic makeup and metabolic pathways.
Structurally, the most notable difference is the composition of their cell walls and membranes. Bacteria usually have a cell wall composed of peptidoglycan, while archaea have cell walls made of a similar substance called pseudo peptidoglycan or other polymers. Additionally, they incorporate different lipid molecules into their cell membranes. These distinctions place these organisms into the separate domains of Bacteria and Archaea.

which atmospheric layer is least dense
The exosphere is the least dense layer of Earth's atmosphere because it is the farthest away from Earth and has the least amount of air molecules.
The exosphere is the least dense layer of Earth's atmosphere.
Here's why:
The atmosphere is made up of five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
As you move away from Earth's surface, the density of the atmosphere decreases. This is because gravity pulls the atmosphere towards Earth, so the closer you are to Earth, the more molecules there are to be pulled in.
The exosphere is the outermost layer of the atmosphere, and it is so thin that it is barely considered part of the atmosphere at all. The density of the exosphere is about 100,000 times less than the density of the air at sea level.
Because of its low density, the exosphere is very cold and has very little air pressure. In fact, the exosphere is so thin that satellites can orbit Earth within it without encountering much air resistance.
The question has eliminated one option exosphere that is only the correct answer.
