Answer:

Viruses can only reproduce after they have infected host cells. Viruses are simply packaged sets of genes that move from one host cell to another. Unlike bacteria and other living parasites, a virus has no structures to maintain—no membranes or organelles needing ATP, oxygen, or glucose.

Answer:

a) Inbreeding

b) Decreased

Explanation:

Florida panther is considered an endangered species that is found in very few numbers in the environment.

In the given question,  

a) The Florida panther scattered in the mountains which could affect the flow of the genes (migration).  When it mated with the other sub-species, it could have led to the inbreeding.

b) Since the lion scattered in the mountains, the gene flow could have occurred and this could have decreased the genetic variation in the population of the Panthers.

Answer:

a) Gene flow in a genetic population is defined as the transfer of genetic variation from one population to another.

Gene flow is considered as one of the impotant mechanism of genetic diversity in a population. Migrant affects the genetic diverisity in a population by modifying the allele frequencies.

When florida Panthers introduced with subspecies of mountain lions it increases the genetic flow in the population of mountain lion as the florida panther were carrying a particular variant of a gene.

B) Due to high genetic flow the genetic vriation in the population will decrease between the two groups and results in increasing homogeneity. High rate of gene flow lead to a combination of the two gene pools that reduces the genetic variation. Hence, genetic variation will decrease in the mountain lion population.

1 all round cells : 2 mixed round and sickled cells : 1 all sickled cells (B) is the correct option.

Sickle cell disease is an inherited blood disorder that affects the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. It causes red blood cells to become misshapen and break down, leading to various health problems.

The possible genotypes of the offspring are SS, Ss, and ss, with respective probabilities of 1/4, 1/2, and 1/4. The corresponding phenotypes are all round cells, mixed round and sickled cells, and all sickled cells, respectively.

Since sickle cell disease is codominant, the phenotype of the heterozygous individuals is a mixture of the phenotypes of the homozygous individuals. Thus, the phenotypic ratio of the offspring is 1 all round cells : 2 mixed round and sickled cells : 1 all sickled cells.

Answer:

The distribution of organisms on the earth's surface is ultimately due to evolutionary change: Organisms or Species do not stay the same over time but are in a constant state of change as individuals. They are best able to live and reproduce within certain environments.

Explanation:

Plz give me brainliest.

The distribution of organisms of a species is constant with respect to time on the surface of the earth.

A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.

Organisms of a particular species evolve with respect to time. A specific organism or species does not stay the same over a period of time. But they acquired constant changes over time. They are favored by the environment to produce fertile offspring.

Explanation:

bio ninja helped out a lot when i took ib bio

Diffusion is the process of molecules moving from an area of high concentration to an area of low concentration. It is important in various biological systems.

The process you are describing is called diffusion. Diffusion is the movement of molecules or ions from an area of higher concentration to an area of lower concentration, down a concentration gradient. This movement occurs because molecules are in constant random motion and tend to spread out to achieve a more even distribution.

For example, when you open a bottle of perfume in one corner of a room, the perfume molecules will eventually spread throughout the entire room. This is due to diffusion.

Diffusion is an important process in various biological systems, such as the exchange of gases in the lungs, the absorption of nutrients in the intestines, and the movement of molecules across the cell membrane.

A. All peas should be green.

B. All peas should be yellow-green.

C. One pea should be green and three peas should be yellow.

D. One pea should be yellow and three peas should be green.

Answer:

C. One pea should be green and three peas should be yellow.

Explanation:

In Mendel’s experiment, the allele for yellow seed color iss dominant, while the green allele is recessive. His experiment involves crossing two true breeding pea plants that are homozygous for various selected traits. For example, for seed color, each of the parent plants are homozygous for each of the seed color. i.e. one is homozygous dominant for yellow seed  (YY), while the other is homozygous recessive for green color  (yy).

The first filial generation gotten from the cross between both parents has all the offspring of the F1 generation having yellow seed color. They were all heterozygous  (Yy), since yellow color is dominant over green color, all F1 individuals appeared similar to their parents and were all had yellow seeds.

When two first-generation offspring were crossed together, the ratio of individuals having Yellow seed color to green seed color was 3:1, meaning a cross between two F1 generation should give us 1 pea plant with green seed color and 3 peas should have yellow.

Homologous structure

Explanation:

Homologous structures refers to organs or bones that have similar anatomical features found in different animals that are suggested to have the same common ancestor and serves as an evidence of evolution.

Whakes, humans and cats have similar bones in the same order but different in function.

Answer and Explanation:

The fact that whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters or homologous structures.

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

Answer:

The answer is B. Indirect!

Explanation:

Answer/Explanation:

I. Cross between a female Gg with a male gg (GG X gg):

1. Probability of getting gray offspring (Gg) = 2/4 (¼+ ¼) = ½  

2. Probability of getting albino offspring (gg) = 2/4 (¼+ ¼) = ½

3. There are 2 possible genotypes among the offspring, which are Gg and gg.

4. There are 2 possible phenotypes among the offspring, which are gray and albino coat color.

5. Probability of getting heterozygous offspring (i.e. Gg) = 2/4 = ½

6. Probability of getting homozygous offspring (i.e. GG or gg) = Probability of getting GG + Probability of getting gg = ½ + 0 = ½  

7. The color of the female that was crossed (i.e. Gg), is gray color. The allele for gray coat color (G) is dominant over the allele for albino coat color (g).

8. The color of the male (gg) that was crossed is albino. The recessive allele (g) for albino coat color, in its homozygous state would express itself in the absence of the dominant G allele for gray color.

II. Cross between homozygous gray female with a heterozygous male (GG X Gg):

1. Probability of getting gray offspring (GG or Gg) = 4/4 (i.e. ¼+ ¼ + ¼ + ¼ ) = 1  

2. Probability of getting albino offspring (gg) = 0  

3. There are only 2 possible genotypes among the offspring, which are GG and Gg.

4. There is only 1 possible phenotype among the offspring, which is gray coat color.

5. Probability of getting heterozygous offspring (i.e. Gg) = 2/4 (i.e. ¼+ ¼ ) = ½

6. Probability of getting homozygous offspring (i.e. GG or gg) = Probability of getting GG + Probability of getting gg = 0 + ½  = ½  

7. The genotype of the female that was crossed is GG, given that the female is homozygous gray.

8. The male crossed is a heterozygous male (Gg), the male is gray.

III. Cross between a gray female, whose father was albino, with a heterozygous male (Gg X Gg):

We can make a good guess of the genotype of the female, given that gray color is dominant over albino, and the father was albino (gg). The father can only contribute sperm having only (g) allele, while the mother must contribute only a (G) allele to give a gray offspring. The gray female is definitely heterogyzous female i.e Gg

1. Probability of getting gray offspring (Gg or GG) =  ¾ (½ + ¼)  

2. Probability of getting albino offspring (gg) = ¼

3. There are 3 possible genotypes among the offspring, which are GG, Gg, and gg.

4. There are 2 possible phenotypes among the offspring, which are gray and albino coat color.

5. Probability of getting heterozygous offspring (i.e. Gg) = 2/4 = ½  

6. Probability of getting homozygous offspring (i.e. GG or gg) = Probability of getting GG + Probability of getting gg = ¼ + ¼ = ½  

7. The genotype of the female is Gg. We know this because we were given that it is gray in color, and gray is dominant over albino. Also, given that the father was albino (gg), a (g) allele can only be contributed by the father to combine with the dominant (G) allele to give us a female that has heterozygous gray coat color (Gg).

8. The genotype of the male is Gg. We know this because we were given that it was a heterozygous male. If an organism is heterozygous, it has different alleles controlling that trait.

IV. Cross between an albino female, whose father was gray, with a gray male, whose mother was albino (gg X Gg):

The albino female’s genotype is gg, because the g allele is recessive. The gray male’s genotype, whose mother was albino (gg) is definitely Gg, because gray is dominant, and to get a gray offspring, a G allele from the mother of the male must combine with the g allele that the albino father can only contribute i.e. Gg or GG from mother X gg from father = Gg (the gray male offspring).

1. Probability of getting gray offspring =  ¼ + ¼ = ½  

2. Probability of getting albino offspring (gg) = ¼ + ¼ = ½  

3. There are 2 possible genotypes among the offspring, which are Gg, and gg.

4. There are 2 possible phenotypes among the offspring, which are gray and albino coat color.

5. Probability of getting heterozygous offspring (i.e. Gg) = ¼ + ¼  = ½  

6. Probability of getting homozygous offspring (i.e. gg or GG) = ½ + 0 = ½  

7. The genotype of the gray father of the albino female (gg) is Gg. Of the two possible genotypes of the gray father (i.e. GG or Gg), Gg is the most likely genotype to contribute the recessive g allele that would pair up with another g allele from the mother to give an albino female (gg), i.e. Gg (father) X Gg (Mother) or Gg (Father) X gg (Mother) = gg (albino female)

A monohybrid cross is a genetic cross that considers only one trait. Results from these crosses led to the concept of dominant and recessive traits and Mendel's Law of Segregation. Punnett squares visually present the likely outcomes of these crosses.

A monohybrid cross involves the mating of individuals who have two different alleles for a single trait. For example, Mendel ran several monohybrid crosses using pea plants. The trait being examined was the color of the pea—the parent plants had either green or yellow peas. After breeding a purebred yellow pea plant with a purebred green pea plant, all offspring were yellow, showing that yellow is the dominant trait and green the recessive.

Monohybrid crosses are useful tools in predicting the outcome of genetic crosses because they follow Mendel's Law of Segregation. According to this law, during the formation of reproductive cells, pairs of genetic traits separate, and offspring receive one factor from each parent.

A Punnett square is a tool that provides a visual representation of the possible combinations of genetic traits the offspring could inherit. For monohybrid crosses, a Punnett square will give a 3:1 ratio, representing the likelihood of the offspring expressing the dominant trait over the recessive trait, given that both parents are heterozygous.

The correct answer is Option C.Water is produced during the electron transport chain, which is a step in aerobic respiration. Alcohol fermentation does not result in the production of water, but instead, it creates ethanol from pyruvic acid.

Water is produced during cellular respiration processes, mainly in the electron transport chain (ETC), which is part of aerobic respiration. The ETC occurs in the mitochondria where oxygen is the final electron acceptor and combines with electrons and protons to form water (H2O). In contrast, during alcohol fermentation, ethanol is produced rather than water. Alcohol fermentation involves the conversion of pyruvic acid to acetaldehyde and then to ethanol, with no production of water. The citric acid cycle (also known as the Krebs cycle) likewise produces high-energy electron carriers but does not directly yield water.
