A) A hognose snake pretends it is dead to trick
a predator. B) A frog's light-colored belly makes it harder
for a predatory fish to see it against sunlight
on the water surface.
C)The scarlet king snake looks very much like
the poisonous coral snake. D) A treehopper on a leaf or twig resembles
a thorn.

The offspring will inherit one allele from each parent.

The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.

One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.

The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.

Now as they are crossed the offsprings will have genetic combination of Yy.

This is seen that the offsprings carry one allele from both the parents.

Answer:

true

Explanation:

Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.

Excessive protein intake can lead to kidney problems, weight gain, and nutrient imbalances.

An excessive intake of protein can have several negative consequences on the body. One consequence is an increased risk of kidney problems, as the kidneys have to work harder to filter and eliminate the excess protein. Another consequence is potential weight gain, as excess protein can be converted into body fat if it is not used for energy. An excessive protein intake may lead to nutrient imbalances, as a diet high in protein may lack other essential nutrients.

Additionally, imbalanced protein consumption can disrupt nutrient ratios in the diet. It is important to maintain a balanced diet and consult with a healthcare professional or nutritionist to determine the appropriate protein intake for individual needs and goals.

An excess of protein in the diet can lead to health complications, especially concerning the kidneys due to the overproduction of glycogen. This unregulated production results from the body's need to use or store the excess, which can create strain and eventually health problems. Therefore, a balanced diet is crucial for maintaining appropriate levels of proteins.

Excessive protein intake, much like an imbalance of any macromolecule in one's diet, can lead to various health problems. A significant consequence of excess protein intake can be related to the kidneys. Consuming an excess of protein can lead to an overproduction of glycogen, which is typically used to produce energy when food resources are scarce.

Normally, proteins are essential for our bodies functioning, being a vital part of the structure of our cells, enzymes, and much more. However, when proteins are present in excess, the body is forced to convert them into glucose or triglycerides in order to use or store them. This unnatural production of glycogen can place undue strain on the kidneys, possibly leading to health problems.

Equally, just as metabolic fuel sources are necessary for functioning, an imbalance can create complications. Therefore, although proteins can serve as potential fuel sources, this is only true when balanced appropriately, highlighting the importance of a well-regulated diet and lifestyle.

The term 'synapsis' is associated with crossing over process.

Explanation:

An exchange or reciprocal segmental switch between chromatids of a homologous pair of chromosomes that results in a gene recombination, is understood as a crossing over. Synapsis is the fusion of two homologous chromosomes occurring while meiosis.

Synapsis enables the alignment of homologous pairs and probable chromosomal fusion between them previous to their division. The synapsis happens during meiosis prophase I. Crossing over takes place during prophase I of meiosis until tetrads are paired in metaphase I along the equator. Even sister chromatids survive by meiosis II, and homologous chromosomes were transferred to separate cells. Notice that the point of convergence is to raising genetic variability.

Answer:

Explanation:

Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single strand folded onto itself, rather than a paired double strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

tRNA, is found in the cytoplasm and is involved in protein synthesis. Transfer RNA transports amino acids to the ribosome, one for each three-nucleotide codon of rRNA. The amino acids can then be combined and processed to form polypeptides and proteins. The template for this is formed by mRNA.

A polypeptide is an unbranched chain of amino acids connected by peptide bonds.

mRNA is the one that make template for protein synthesis. tRNA is a protein synthesis enzyme found in the cytoplasm.

Transfer RNA, one for each three-nucleotide codon of rRNA, transports amino acids to the ribosome. After that, the amino acids can be combined and processed to create polypeptides and proteins.

Thus, in this way the three RNA works together to form a polypeptide.

Answer:

C. Burning coal for electricity.

Explanation:

When fuels like wood, coal petroleum and natural gas are burnt, the carbon in them is oxidized to carbon dioxide which returns to the atmosphere. Coal, petroleum and natural gases are known as fossil fuels. Coal comes from the partly decayed remains of ancient plants that became buried millions of years ago and were subjected to great pressure. As these fossil fuels take time millions of years to form, the carbon in them tends to recycle very slowly. In as much as they take time to form, they are been used up rapidly.

Biodiversity can be impacted by the increase or decline of the elephant population. This can result in either a decrease or disruption of biodiversity in the ecosystem.

Biodiversity refers to the variety of life forms in an ecosystem, including different species and their genetic variations. The increase or decline of the elephant population can have significant effects on biodiversity.

If the elephant population increases, it could lead to a decrease in biodiversity in the ecosystem. Elephants are mega herbivores that require large amounts of food and space. As their population grows, they may overgraze or trample vegetation, leading to decreased species diversity and habitat loss for other organisms.

On the other hand, a decline in the elephant population can also negatively impact biodiversity. Elephants play a crucial role in ecosystem dynamics through their feeding habits and seed dispersal. When elephant numbers decline, it can disrupt plant communities and reduce the availability of food and resources for other species, leading to a decrease in biodiversity.

Elephant populations increase in African nations with property rights and stable political systems, but decline due to poaching and habitat loss, despite the international ivory trade ban.

The relationship between biodiversity and elephant populations is multifaceted, demonstrating both how measures to protect these animals can lead to their population increase and how various threats contribute to their decline. An analysis by Professors McPherson and Nieswiadomy illustrated that elephant populations have increased in African nations with established property rights and stable political systems, which can include exclusive, transferable licenses to hunt elephants. Nations like Botswana and Zimbabwe are examples where such practices have led to significant rises in elephant numbers.

Conversely, in cases where these conditions are not met, and especially with the impact of human activities such as poaching and habitat encroachment, elephant populations are in decline. Forest elephants, even in isolated national parks, have suffered from poaching and range reduction despite international agreements like CITES, which banned the trade in ivory. The challenges also include ethical debates over culling, effects on habitats, and conflicts with human interests, which all play a role in the conservation and management of elephant populations.

Hello!

I will use a capital letter to demonstrate dominant (B) and lowercase letter to demonstrate recessive (b).

The given scenario would only be possible of both of the parents had heterozygous genes (Bb), meaning that they have one dominant allele and one recessive allele.

The offspring will only exhibit a recessive trait if that particular gene has two recessive alleles (bb). If both parents have only one recessive allele (Bb), then neither will exhibit the recessive trait.

It is possible, however, that each parent will pass on their one recessive allele. In this case, the offspring would now have two recessive alleles (bb) and begin exhibiting the recessive trait.

I hope this helps!

Answer: it is possible for an offspring to exhibit a recessive trait if neither parent exhibited that recessive trait if both parents are heterozygous for the trait. The parents' genotype must be heterozygous i.e., having one dominant allele and one recessive allele.

Explanation: It is possible for an offspring to exhibit a recessive trait when neither of the parents exhibited the recessive trait.

For example, if (A) is the allele for normal skin colour and it is dominant to (a) which is the allele for albinism that is recessive, two parents with heterozygous genotype Aa will have offsprings with the following possible genotypes: Aa x Aa = AA, Aa, Aa and aa.

One of the offsprings will inherit recessive allele for albinism from each parent (aa), and thus will manifest outwardly as albino child.

Answer:

Crossing over occurs between prophase I and metaphase I and is the process where two homologous chromosome non-sister chromatids pair up with each other and exchange different segments of genetic material to form two recombinant chromosome sister chromatids.

Before crossing over can occur in meiosis, homologous chromosomes must line up during prophase I, and DNA replication must have taken place to form sister chromatids. Crossing over involves precise DNA exchanges between non-sister chromatids, and is critical for genetic diversity and integrity.

Before crossing over can occur in meiosis, several steps must take place. Firstly, during prophase I, the homologous chromosomes line up together. This alignment is crucial because it sets the stage for the exchange of DNA between these paired chromosomes. Before the exchange, the DNA must be replicated to form sister chromatids, and the chromosomes condense and coil up tightly. During prophase I, crossing over occurs when a double strand break on one DNA molecule is joined with a double strand break on another, allowing the exchange of genetic material between non-sister chromatids, typically at the same relative locations.

The accuracy of crossing over is vital for maintaining genetic integrity, as it must be done with precision to prevent the gain or loss of genes. Any inaccuracy, such as a frameshift mutation, could result in a defective gene product or no product at all. Crossing over not only assists in holding the chromosomes together until they separate in anaphase I, but it also facilitates genetic recombination between linked genes. After crossing over, during metaphase I, the homologous chromosomes randomly assort on the metaphase plate, further contributing to the unique genetic makeup of the resulting gametes.
