Answer:

People can be immunised against a pathogen through vaccination. Different vaccines are needed for different pathogens. For example, the MMR vaccine is used to protect children against measles, mumps and rubella (German measles).

Answer:

1. Probability is 1/2

2. Parents phenotypes:

TTHh = white spots, short hair

Tthh = white spots, long hair

Explanation:

This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).

According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:

TTHh - TH, Th, TH, Th

Tthh - Th, Th, th, th

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:

TTHh = white spots, short hair

Tthh = white spots, long hair

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

Answer:genotypes

Explanation:

Answer:

This question lacks options, the options are;

A) In codominance and incomplete dominance, both of the alleles are dominant.

B) In codominance and incomplete dominance, neither of the alleles are dominant.

C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.

D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.

The answer is C

Explanation:

Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.

- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.

- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.

The correct answer is b

Explanation:The young goat inherited its copies of the gene for horn shape from its mother and not from its father. Those genes connect together to make its downward-curved horns.

Answer:

How you approach and talk to the person you like

Explanation:

If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand)  for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

Answer:

The water quality is good because they are both sensitive to pollution

Explanation:

The quality of the water is extremely fine when you see caddis fly larva and freshwater shrimp.

The quality of water is determined by analyzing several properties like dissolved oxygen, pH, suspended particulate matter, pollution estimation, density, etc.

The member of caddis fly larva and freshwater shrimp always found in the aquatic environment where there is less or no pollution.

These species are adapted to the freshwater ecosystem and hence commonly found in fine quality of water.

Therefore, the quality of the water is extremely fine when you see caddis fly larva and freshwater shrimp.

You gotta sketch out a sperm egg under the questions after the example.

Explanation:

You see, there is an example, right? Well, then, depending on how many chromosomes there are, write the correct chromosome number in each cell. Number 1 is just an example of what you gotta do. Mosquito wing cell contains 6 chromosomes. The cell contains at least 42 chromosomes. Do what you saw in the example: egg cell gamete + cell gamete = 1st somatic cell.

A. Crossing over

During synapsis in meiosis (when the homologous chromosomes pair together during prophase I), is when crossing over occurs, and the chromatids of the homologous pairs "cross over" and swap genetic material.

Answer:

Each of the offspring is genetically unique and received some of its genetic

Explanation:

While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.

While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.

So, Each of the offspring is genetically unique and received some of its genetic  information from each parent, so each has some traits in common with each parent.

The three components that make up the structure of the atom are as follows:

The nucleus of an atom may be defined as the center of any atom that significantly consists of protons and neutrons.

Due to the positive charge on protons and neutral charge on neutrons, the nucleus of an atom is found to be positively charged.

The electrons are negatively charged sub-atomic particles which are always revolving around the nucleus of an atom.

While protons are positively-charged sub-atomic particles that are present in the nucleus of an atom. And Neutrons are neutral or no charge sub-atomic particles that are present in the nucleus of an atom along with protons.

Therefore, the three components of atom has been significantly described with respect to their charge and specific locations within atom.
