Hybridization _____.
occurs frequently in nature
is the process of gene combination in a lab
usually produces offspring that cannot reproduce
creates genetically identical offspring
Answer:
The correct answer is: c) usually produces offspring that cannot reproduce.
Explanation:
Hybridization, also knowns as selective breeding, is an artificial process that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits.
Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.
Option A is incorrect because hybridation does not occur in nature, it is an artificial process.
Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).
Option D is correct because an important amount of hybrids are sterile (for example: mules).
Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.
Answer:
usually produces offspring that cannot reproduce
Explanation:
Hybridization is the process of crossing two organisms usually of different species, genus or families but of desirable characters to produce organisms known as hybrids.
Hybrid organisms combine the characteristics of both parents and because of the difference in genetic composition of the parents, they are often sterile and hence, cannot reproduce.
Therefore, hybridization usually produces offspring that cannot reproduce.
During DNA replication, each strand of DNA is used as a template to produce
a complementary strand of DNA. This process is shown below. Which base
will attach to location 2?
A. Allimene
B. Adenine
c. Thymine
D. Tyrosine
Answer:
The correct option is C) Thymine
Explanation:
The model of the DNA is made up of two strands of DNA which are complementary to each other. The sugars and phosphates make up the back bone of the DNA and the nucleotides make up the inner parts which are joined through hydrogen bonds. Adenine pairs with thymine. Cytosine pairs with Guanine.
As the nucleotide present at location 2 is adenine, hence thymine will be the base which will pair with it.

Therefore, density of the wooden cube is 0.8 g/cm³
Explain why each chromosome must become two strands before the cell divides.
Answer:
To allow transcription enzymes to access the DNA strand
Explanation:
The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.
DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.

Rr
Heterozygous Red- Rr
Homozygous Red-- RR
Homozygous white-- rr
Monohybrid cross- Rr
Recessive allele- homozygous white i.e rr
Explanation:
Heterozygous have 2 different alleles of a gene as both Red and white alleles are present in the example Rr.
Homozygous: If the 2 alleles at a locus is same then they are homozygous, it can be dominant as RR or recessive as rr.
Recessive gene are the ones that can be masked by the dominant genes as red is dominant on white.
Monohybrid cross is the result of cross between the individual having either homologous dominant or recessive genes or genotype. The result is generally masking the recessive allele resulting in dominant phenotypic trait but the genotype changes.
From the example given in question:
A cross between dominant red as RR
and a cross between recessive white as rr
The punnet square shows:
r r
R Rr Rr
R Rr Rr
it can be seen that all progeny are red but genotype changed to heterozygous red as Rr
(c) Name all the classes of Chordata which is warm-blooded (endothermic).
The classes of chordata which are warm-blooded are birds and mammals.
Explanation:
Warm-blooded animals are those which can maintain their body temperature at a constant.
These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.
The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.
Warm blooded animals cool themselves with the help of sweat glands.
The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.
These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.
Whale living in water is the fish which is also warm blooded because it is a mammal.

what cellular process allows plants and animals to convert glucose in atp energy
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Final answer:
Cellular respiration is the process by which plants and animals convert glucose into ATP, with glycolysis, the citric acid cycle, and oxidative phosphorylation being the main stages.
Explanation:
The cellular process that allows plants and animals to convert glucose into ATP energy is known as cellular respiration. This metabolic process is crucial for life, as ATP acts as the energy currency for cells, powering various cellular activities. Cellular respiration begins with glycolysis in the cell's cytoplasm, where glucose is partially broken down. Then, inside the mitochondria, the process continues through the citric acid cycle and concludes with oxidative phosphorylation, producing ATP.
Both plants and animals perform cellular respiration, although plants also create glucose through photosynthesis using sunlight. The oxygen used in cellular respiration yields water and carbon dioxide as byproducts, which are, in turn, utilized by plants to perform photosynthesis, thus creating a cycle of energy transformation within the ecosystem.

Meiosis II is ______________________ division which produces _______________ nuclei in _____________________ cells for a total of __________________ nuclei.
Meiosis II is reduction division which produces four nuclei in 4 haploid cells for a total of four nuclei.
Explanation:
Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.
It comprises following stages:
prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.
metaphase II : The chromosomes are lined at metaphase plate.
Anaphase II: the sisters chromatids gets pull apart.
telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.
Meiosis II is the division that produces haploid nuclei in four cells, resulting in a total of four haploid nuclei.
Meiosis II is the second stage of meiotic cell division, following meiosis I. It is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes. During meiosis II, the primary objective is to further reduce the chromosome number in each cell, ensuring that the resulting gametes are haploid.
Meiosis II involves the separation of sister chromatids, which were produced during meiosis I. This separation process occurs in four daughter cells, each with half the number of chromosomes as the original parent cell. Therefore, meiosis II is a division that produces haploid nuclei in haploid cells. In total, meiosis II produces four nuclei, each contained within a separate daughter cell.
The process of meiosis II is crucial for maintaining the haploid state of gametes, ensuring that when fertilization occurs, the resulting zygote has the correct diploid chromosome number. Additionally, meiosis II contributes to genetic diversity through processes such as independent assortment and crossing over during meiosis I, leading to unique combinations of genetic material in each gamete.
Danielle has blue eyes. Which term describes her
eye color?
Answer:
he has blue eyes because of his genes
Explanation:
danielle has blue eyes because one of his parents would have blue eye color and danielle contains that parents gene for eyes that's why he has blue eye.
Final answer:
Eye color, such as Danielle's blue eyes, is determined by complex hereditary patterns in biology; it results from the interactions of multiple genes contributing to the phenotype of an individual's eye color.
Explanation:
The term that describes Danielle's eye color, which is blue, pertains to the concept of genetics in biology. Eye color is determined by multiple genes and is a result of complex inheritance patterns, often referred to as non-Mendelian inheritance. These patterns involve various genes contributing to the phenotype of an individual's eye color, making it possible for a range of eye colors including green, blue, brown, black, hazel, violet, or grey. The pigment responsible for blue eye color is due to the lack of melanin in the stroma of the iris, which causes light to scatter in a way that makes the eyes appear blue.

Answer:
Explanation:
Physical weathering, also known as mechanical weather, is the process of rocks and minerals on Earth's surface breaking down or dissolving as a result of water, ice, salt, plants, animals or changes in temperature. Physical weathering does not change the chemical composition of the rock, just cracks and crumbles it into smaller pieces. After a rock has weathered, erosion occurs, transporting bits and pieces away. Finally a deposition process deposits the rock particles in a new place.
Physical weathering by plants, wind, and ice rock fragments to their new location. Water flowing quickly Ice wedges numerous rocks break as a result of ice plant roots can spread.

C.keratin
D.sugar
Answer:
The answer to your question is D, Sugar
Final answer:
The correct option for a carbohydrate that stores energy is D. sugar, which includes glycogen, a polysaccharide used by animals for short-term energy storage.
Explanation:
Carbohydrates are fundamental biological molecules that serve various roles, including energy storage. An essential simple sugar, glucose, shows the compact and immediate energy supply carbohydrates can provide. However, for longer-term storage, animals use a polysaccharide known as glycogen. Glycogen is made from hundreds or thousands of glucose units and is particularly abundant in liver and muscle cells. It serves as an energy reserve and is utilized when the body is fasting to maintain metabolic balance. Unlike fats or proteins, glycogen can supply the energy quickly due to its more accessible structure for enzymatic breakdown. This is why glycogen is a primary form of energy storage in animals.
The correct option from the list provided that is an example of a carbohydrate that stores energy is D. sugar. The sugars, specifically in the form of glycogen, are utilized by our bodies for short-term energy storage. This is in contrast to fats, which serve as long-term energy reserves but are not carbohydrates.

Write two examples of conclusions Mendel reached about inherited traits after completing his experiments with pea plants.
WILL GIVE BRAINIEST
Final answer:
Mendel reached two conclusions about inherited traits: the Law of Segregation and the Law of Independent Assortment.
Explanation:
Mendel reached two conclusions about inherited traits after completing his experiments with pea plants:
Law of Segregation: Mendel observed that the two alleles for each trait separate during the formation of sex cells. This means that each parent contributes one allele for a specific trait to their offspring. For example, when a plant with yellow smooth peas is crossed with a plant with green wrinkled peas, the resulting offspring will inherit one allele for pea color (either yellow or green) and one allele for pea texture (either smooth or wrinkled).
Law of Independent Assortment: Mendel found that the inheritance of one trait is not influenced by the inheritance of another trait. For instance, the alleles that code for different traits, such as pea color and pea shape, sort independently during meiosis. This means that the expression of one trait does not affect the expression of another trait in the offspring.
