4. What is a chromosome?
Answers
how many chromosomes are there in human ovum
Answers
Answer:
23 chromosomes
Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes.
Explanation:
have a good day!
(─‿─)
The chromosomes in egg and sperm cells have just 23 chromosomes each.
What is gamete?Male gametes are termed sperm, while female gametes are called "ova." Gametes are an organism's reproductive cells, also referred to as "gender cells." Since gametes are haploid cells, each chromosome is present in one copy per cell.
Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized. Gametes are always haploid cells since they are a byproduct of meiosis.
Zygote is a diploid structure because it results from the fusing of a male and female haploid gamete.
Similar to a sperm, an egg has 23 chromosomes total, which is half the number found in a normal cell.
The resultant embryo will therefore have the typical 46 chromosomes in total after an egg and sperm join during fertilization.
Thus, there are 23 chromosomes in human ovum.

Which of the following is carried out by vesicles?
O Synthesizing proteins
O Facilitated diffusion
Breaking down substances within the cell
Organizing organelles prior to division
Answers
Answer:
breaking down substances within the cell
Explanation:
there are many different types of vesicles, Peroxisomes and lysosomes are both types that break down substances in the cell
The correct statement about vesicles is "Breaking down substances within the cell"
Vesicles are an organelle isolated from the cytoplasm by a membrane-like lipid layer.
Its function is to store, move and process products and cellular waste.Endocytosis and exocytosis transports are characterized by the fact that the substances move through vesicles.The vesicles incorporate substances (endocytosis) and through degradation, they expel large particles that cannot cross the plasma membrane, this mechanism is exocytosis.Therefore, we can conclude that the cell incorporates, inside the vesicle, particles from the extracellular environment and also through the vesicles it releases degradation products to the extracellular environment.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children with type o. what blood type should he request on his dating survey? what must Opine’s blood type be in order to produce offspring with type O blood?
Answers
Answer:
He should request type O on his dating survey.
Opine's blood type must be AO to have a higher probability of producing O offsprings.
Explanation:
O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.
O blood type results are possible thanks to OO genotypes.
If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.
As regards the mother, her blood type should be OO.
We can see this more clearly in Punnet Square.
║ A ║O
O║AO║OO
O║AO║OO
There is a 50% of probability of having O offsprings with AO and OO.
║ A ║A
O║AO║AO
O║AO║AO
With AA and OO, the probability is 0%
║ A ║O
A║AA║AO
O║AO║OO
With both parents having AO, blood the probability of having a OO offspring is 25%.
In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.

Cystic fibrosis is a recessive genetic disease caused by a mutation in the gene that encodes the CFTR protein, which transports chloride ions in and out of cells. Some populations have a relatively high rate of cystic fibrosis carriers, possibly because the mutation protects against severe dehydration in diseases like cholera or typhoid. What concept does this best illustrate?
A: Polygenic traits
B: Genetic drift
C: Pleiotrophy
D: Heterozygote advantage
Answers
its letter b the genetic drift because it is mechanism of evolution in which allele frequencies of a population change over generation due to chance.
Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D.
What is the heterozygote advantage?When the gene is present in a heterozygote state, the gene product benefits the individual rather than harming him or her, as in sickle cell anemia and cystic fibrosis. In sickle cell anemia, the heterozygote state protects the person from malaria, and in cystic fibrosis, it protects the person from dehydration.
Hence, Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D..

It also facilitates establishing the dates of phylogenetic events including those not documented by fossils.
The molecular clock technique is an important tool in molecular systematics. It helps to determine the correct scientific classification of organisms by deriving information from molecular genetics.
Hope this helped :) please mark brainliest
Answer:
A) A molecular clock is a measure of evolutionary time based on the theory that specific DNA sequences mutate at constant rates. To use a molecular clock, scientists first select two different species and compare their DNA sequences. They can compare the DNA sequences directly, or by looking at the RNA and protein molecules created from the DNA. Molecular clocks help to measure the number of changes and mutations which accumulate in the gene sequence of different species over a period of time.
B) Molecular clocks assume the neutrality of gene mutation. They are based on the fact that genetic mutations although random, occur at a relatively constant rate. Evolutionary biologists use this information to deduce how species evolve and determine when two species diverged on the evolutionary time line. It is useful in the study of variations in selective forces, and also facilitates establishing the dates of phylogenetic events including those not documented by fossils. Molecular clocks do have some limitations. Rates of change may not be constant, may not be the same in all organisms, and may be different for different genes.

The introduction of Caulerpa, also known as killer algae, into California was ultimately the result of the aquarium trade in exotic, nonnative aquatic species. The correct option is b.
What is exotic species?Exotic species are those that have been introduced, either intentionally or unintentionally, by humans into an ecosystem where they did not evolve. Such introductions are most likely a natural occurrence.
Endemic species are those that are found only in one region and nowhere else on the planet.
Invasive species have the potential to extirpate native plants and animals, reduce biodiversity, compete with native organisms for limited resources, and alter habitats.
This has the potential to have significant economic consequences as well as fundamental disruptions to the coastal and Great Lakes ecosystems.

The amount of energy at each trophic level in an ecosystem decreases as it moves through the ecosystem. Typically, only about 10 percent of the energy at one trophic level is transferred to the next level. The remaining energy is lost through metabolic processes as heat.
Suppose that, in the ecosystem modeled above, 150,000 kcal (kilocalories) of energy are contained within green plants. Assuming that the amount of energy transferred from one trophic level to the next is exactly 10 percent, determine the following amounts of energy in the ecosystem.
Answers
Answer:
Explanation:
Energy transferred to next trophic level=10%×150,000kcal
=10/100×150,000
=15,000kcal
The amount of the energy in the ecosystem should be considered as the 15,000kcal.
Calculation of the amount of energy:Since there is 150,000 kcal (kilocalories) of energy are contained within green plants.
And, 10 percent of the energy at one trophic level is transferred to the next level.
So here the amount of energy be like
= 10% of 150,000
= 15,000 kcal
Hence, The amount of the energy in the ecosystem should be considered as the 15,000kcal.

Explanation:
The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g., β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.
