During meiosis I, how could you have arranged the chromosomes in a different way? How do the differences affect the end result of meiosis??
Explanation:
Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.
Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.

ome people have dimples; other people do not. Having dimples is dominant over not having dimples.
If the allele for having dimples is represented with the letter D, what allele combinations can result in having dimples?
In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS
Answer:
Genotypic ratio = 16 WwDd: 0
Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit
Explanation:
This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).
According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:
WWDD - WD, WD, WD, WD
wwdd - wd, wd, wd, wd
Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.
The genotypic ratio is 4 WwDd: 0
The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

Answer:
Organelle 1
Explanation:
This is the nucleus which stores dna, which would determine blood type.
Organelle 1 is called as the nucleus that stores DNA, which would determine blood type. So, the correct option is A.
What is Nucleus?The membrane-enclosed organelle in a cell that houses the chromosomes is known as the nucleus. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such proteins and nucleic acids) inside and outside the nucleus.
The cytoplasm and nucleus's contents are separated by the membrane. The chromosomes of the cell are also included within it. The chromosomes, which contain DNA, supply the genetic data necessary for the synthesis of various cell components as well as for the replication of life.
It regulates the cell's growth and reproduction and holds the genetic information. The genetic makeup of a cell is contained in the nucleus, which has been explained in detail as a membrane-bound structure.
Therefore, the correct option is A.

Research on laboratory rats suggests that hunger is controlled by the
A. prefrontal cortex
B. hypothalamus
C. amygdala
D. cerebellum
Please select the best answer from the choices provided
Answer:
b hypothalamus
Explanation:
The hypothalamus controls hunger and satiety. Therefore, option (B) is correct.
What is the role of hypothalamus?
The hypothalamus regulates circadian rhythms, appetite, thirst, and body temperature. The study of illnesses and diseases associated to the neuroendocrine system may benefit from using rat hypothalamic neurons.
The arcuate nucleus, or infundibular nucleus in humans, is a region of the hypothalamus that permits peripheral peptides and proteins to cross the blood-brain barrier and interact with its neurons.

can someone please answer these two questions correctly? thank you so much!! ((:
Explanation:
1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).
2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.

Explain why an area with extreme temperatures like one in the Arctic would be resistant to invasion by a biotic disturbance.
Answer:
Negative responses protect our body by taking the deviation and making it less harmful to the body. When you cut your finger and lose blood, negative feedback kicks in to slow and stop the flow of blood.
The reason of area having high temperatures should be because of the negative response.
Reason of area with extreme temperatures:Due to the negative response, it protect our body by considering the deviation and it make less harmful to our body.
Also, when you cut the finger and blood comes so there is the negative feedback that kicks for stopping the blood flow.

A space used in industry or research settings that has a controlled level of contaminants is called a __________.
Answer:
Clean room.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.
A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

While frying French fries, Wanda burned her hand. Burns are examples of a:
skin abnormality.
homeostatic balance.
skin infection.
homeostatic imbalance.
Answer:
Damage to the skin or deeper tissues caused by sun, hot liquids, fire, electricity, or chemicals.
The degree of severity of most burns is based on the size and depth of the burn. Electrical burns, however, are more difficult to diagnose because they're capable of causing significant injury beneath the skin without showing any signs of damage on the surface.
