If an organism is heterozygous for a particular trait, the organism
A.
has the same allele on both chromosomes in a chromosome pair.
B.
is missing alleles on the chromosomes in a chromosome pair.
C.
has different alleles on the chromosomes in a chromosome pair.
D.
has extra alleles on both chromosomes in a chromosome pair.

Answers

Answer: C.

has different alleles on the chromosomes in a chromosome pair

Explanation:

Hetero means different.

A heterozygous condition is one in which the child inherits various eye-color genes from both biological parents. For that particular gene, a heterozygous genotype exists when there are two distinct versions. Thus, option C is correct.

What is the particular trait for heterozygous organism?

When two distinct alleles of a gene (one mutant allele and one wild-type allele) are present in a diploid organism's cells, that organism is said to be heterozygous at that particular gene locus.

Heterozygosity describes a particular genotype, since the cell or organism is referred to be a heterozygote just for the particular allele in question.

The heterozygote may, however, occasionally have a phenotype that is somewhere between the phenotypes of both homozygous parents.

Therefore, has different alleles on the chromosomes in a chromosome pair.

Identify the advantages and disadvantages of internal and external fertilization

Answers

When a sperm fertilizes an egg within the female, it is known as internal fertilization. The advantages of internal fertilization are that the fertilized egg is protected from predators and harsh environments, thus ending in higher chances of survival. Also, there is a lesser chance of desiccation of gametes. Disadvantages of internal fertilization are that there are lesser number of offspring produced at a given time because it is sometimes difficult for the male and female to come into intimate contact. Additionally, the risk of sexually transmitted diseases also increases.

Every cell contains DNA. The main purpose of DNA is to store the cell’s genetic information. How does DNA control the cell?
A. DNA activates nerve signals in the nervous system
B. DNA speeds up chemical reactions and lowers activation energy
C. DNA protects the cell from invaders.
D. DNA determines what proteins are made.

Answers

Answer:

The answer is D: DNA determines what proteins are made.

Explanation:

The nucleotide sequences that make up DNA are a “code” for the cell to make hundreds of different types of proteins; it is these proteins that function to control and regulate cell growth, division, communication with other cells and most other cellular functions.This process is called protein synthesis.All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

Hope this helps!! ;)

DNA controls the cell by determining what protein are synthesized by the cell. Thus, the correct option is D.

What is Translation?

Translation is the process of synthesis of proteins from the mRNA (messenger RNA) of the cell. This process occurs in the ribosome of the cell. In this process, the mRNA produced from the DNA encodes amino acids which join together to form large polypeptide and protein molecules.

mRNA are produced from DNA through the process of transcription. Transcription occurs in the nucleus of the cell. Through this process, DNA produces a sequence of mRNA which is complementary to it. This mRNA determines what proteins will be synthesized by the cell.

Therefore, the correct option is D.

Anaerobes carry on whereas aerobes carry on cellular respiration

Answers

Answer:

Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.        

Explanation:

Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

Aerobic Respiration

Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

Anaerobic Respiration

Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.

List some
examples of adaptive evolution:

Answers

Answer:

The changes are the organism's adaptive traits and they arise as a result of natural selection. An example of adaptive evolution is the horse's teeth. Its teeth are one of the traits that made it fit for a grass diet. In contrast, genetic drift produces random changes in the frequency of traits in a population

Explanation:

Answer:

I will give you 5 of them :)

1.Flightless Birds

Birds such as ostriches, emus and penguins are unable to fly. However, this hasn't always been the case — each of these flightless birds has ancestors who easily flew. Over many generations, ostriches and emus evolved to have larger bodies and feet made for running on land, which left them without the ability (or need) to fly. The same goes for penguins, who traded typical wings for swim-friendly flippers over many thousands of generations.

2.Blue Moon Butterfly

The Blue Moon Butterfly on the Samoan islands was attacked by a parasite, which destroyed male embryos. This changed the balance of male and female but that was remedied within 10 generations. This is because the few male moths that were immune lived to breed.

3.Mexican Cavefish

Mexican cavefish once had eyes, but in the caves, eyes were no longer necessary. They have also lost their pigmentation because they no longer need camouflage from predators. This is an example of regressive evolution, the belief that "if you don't use it, you lose it" when it comes to traits.

4.Warrior Ants

These ants have a chemical signal that identifies their colony. Some ants learned to imitate this signal from another colony, so they can attack a colony and take over. The worker ants will not even realize there has been an invasion and continue to work.

5.Pesticide Resistant Insects

Whenever you use a pesticide, it kills the majority of an insect population. However, certain insects will experience a gene mutation to develop immunity to it and those insects will reproduce. This happens very quickly, within a few generations, since the generation length for insects is short.

Explanation:

The changes are the organism's adaptive traits and they arise as a result of natural selection. An example of adaptive evolution is the horse's teeth. Its teeth are one of the traits that made it fit for a grass diet. In contrast, genetic drift produces random changes in the frequency of traits in a population

Some chemical reactions release energy. Others store energy. What important chemical reaction stores energy?​

Answers

Answer: endothermic reaction.

Explanation: A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart.

Chemical reactions which release energy are called Exothermic reaction whereas the reaction which store energy are called Endothermic reaction. The energy is stored in the form of chemical bonds.

What is Chemical reaction?

A chemical reaction is a process in which chemical transformation of one set of substance is converted into another type of substance.

Chemical reactions are of two types on the basis of energy transfer: Exothermic reaction and Endothermic reaction. An exothermic reaction is the chemical reaction in which the product is formed with the release of energy in the form of heat. For example: Breakdown of glucose through cellular respiration. An endothermic reaction is the chemical reaction in which the product is formed which stores energy in the form of chemical bonds. For example: The formation of glucose.

How would a lack of contact inhibition result in the growth and spread of cancerous cells?

Answers

Explanation:

Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells

Contact inhibition is the property of normal healthy cells where the cells cease growth after coming in contact with each other. A lack of this property results into uncontrolled growth of cells.

What is Contact inhibition?

Contact inhibition is the property of normal healthy cells which enables the cells to cease proliferation and growth when they come in contact with each other. This property is lost by the cell when the cells undergo malignant transformation. As a result, this leads to uncontrolled proliferation and solid tumor formation in the body.
