Explain how the number of chromosomes per cell is cut in half during meiosis in which the diploid parent cell produces haploid daughter cells.
please help short answer, please 50 points please don't copy my life depends on this
It happens through 3 stages
InterphaseMeiosis 1Meiosis 2In Meiosis one the cell produces diploid daughter cells by combining homogeneous and heterogeneous chromosomes.
In Meiosis two these diploids again tear apart to produce haploid daughter cells
Which of the following is true about adaptation?
I. It is random.
II. It results from genetic mutations.
III. It only affects an individual in a population.
I, II, and III
I and II
II and III
I only
Answer: I and II
Explanation: so basically, when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities, Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.
Species that can live in many different places and eat a variety of food are
K-selected species
r-selected species
specialist species
generalist species
Answer:
generalist species
Explanation:
Specialists eat only one type of food, but generalists will eat many kinds of food. K-selection and R-selection have to do with reproduction, not nutrition.

Which chemical compund is formed during photosynthesis ?
Answer: carbon dioxide / CO2
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose

Which of the following best explains this pattern of inheritance?
A) A sperm or egg carries only one allele for each inherited trait because allele pairs segregate during gamete production.
B) There are alternative forms of genes that account for variation in inherited characteristics.
C) If the two alleles of an inherited pair differ, then one determines the organism's appearance and is the dominant allele.
D) For each characteristic, an organism inherits two alleles, one from each parent.
The statement that best explains the pattern of inheritance described above is that if the two alleles of an inherited pair differ, then one determines the organism's appearance and is the dominant allele (option C).
What is an allele?Allele is the alternative form of the same gene occupying a given position, or locus, on a chromosome.
According to Gregor Mendel in his law of inheritance, he deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Dominant alleles are alleles that are physically expressed while the recessive alleles are those that are masked by the dominant alleles.
According to this question, Mendel discovered that one parent's trait disappeared in the F1 generation of his experiment, only to reappear in one quarter (¼) of the F2 generation.
This is as a result of the concept of dominance or recessiveness in the allele encoding the particular trait. The dominant allele expressed itself over the recessive one in the F1 generation.

Explain why cellular respiration releases energy as an overall chemical reaction
Answer:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP
In other words:
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

If the puppy is growing out fur, for up to 3 weeks, this is normal, some dog breeds need different coat growth times.
What is good for a dog's fur to grow?There are supplements to improve the dog's hair and others that guarantee a general improvement for the health of your companion. Vitamin complexes and essential fatty acids are the most common and recommended. Always look for a veterinarian to indicate the best supplement for your case.

How are 2 different dogs breeds different from a species ?
Answer:
The fact human skip them apart is crucial here. this is a commonly defined as "groups of interpreting natural populations that are reproductively isolated from other such groups."
Is the highlighted group a class or a clade?
A.
It is a clade, because not all of the descendants of the ancestral species are included.
B.
It is a class, because not all of the descendants of the ancestral species are included.
C.
It is a clade, because the cladogram does not show that the group is descended from a common ancestor.
D.
It is a class, because the cladogram does not show that the group is descended from a common ancestor.
Although we do not have access to the diagram to provide a complete answer, we can confirm that a clade is when all members of the group being highlighted belong to a common ancestor.
What is a clade?As stated, this is when the members of a depicted group belong to the same ancestor. It would be a clade if the organisms present are all descendants of a common ancestor, such as the class Aves or birds.
Therefore, we can confirm that a clade is when all members of the group being highlighted belong to a common ancestor.
