Answer:
amygdala
Explanation:
Answer:
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. Epinephrine or adrenalin released by medulla of the adrenal glands, surges at the time of panic and emergency. It provokes stress response and brings out the arousal of extreme emotions like fear, anger or amusement.

All 37 trillion cells in the human body came from?
Answer:
all 37 trillion cell in the body originates from a single fertilized egg called a zygote. The zygote divides repeatedly to produce an embryo. These embryonic cells continue to divide, differentiating into all the cell types present in the body of all humans (and other mammals), from a new-born baby to an elderly adult.
Why do multicellular organisms perform mitosis and meiosis ?
Answer:
Multicellular organisms depend on mitosis for growth and repair. When an animal, plant or other multicellular organism grows, it makes more cells through mitosis. Organisms can repair some of their tissues, using mitosis to regenerate new cells.

Describe the role of DNA helicase, DNA polymerase and DNA ligase in DNA replication.
Answer:
a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.

How do the posterior pituitary gland and the anterior pituitary gland differ in structure ?
The anterior pituitary receives signalling molecules from the hypothalamus, and in response, synthesizes and secretes seven hormones. The posterior pituitary does not produce any hormones of its own; instead, it stores and secretes two hormones made in the hypothalamus.
Answer:
they differ like

The anterior pituitary receives signalling molecules from the hypothalamus, and in response, synthesizes and secretes seven hormones. The posterior pituitary does not produce any hormones of its own; instead, it stores and secretes two hormones made in the hypothalamus.

In cats, long hair is completely dominant to short hair. Jack the cat, his mother, and his sister are all short-
haired cats. With just this information is it possible to know if Jack's dad is a short hair or long hair cat? Why
or why not?
his dads hair is short.
if long hair is completely dominant then Jack's hair would be long if his dads hair was long.
A student examines a thin section of an onion-root tip and records the number of cells that are in each stage of the cell cycle. She observes 93 cells in interphase, 15 cells in prophase, 4 cells in metaphase 6 cells in anaphase and 2 cells in telophase. If the complete cell cycle in an onion-root tip cell requires 24 hours, what is the average duration of each stage in cycle?
Answer:
given:
Total number of cells in all stages = 93+15+4+6+2 = 120
Total time = 24 hours.
solution:
Percentage of cells in interphase
= 93 * 100 / 120 = 77.5%
in prophase
=15 * 100 / 120 = 12.5%
in metaphase
= 4 * 100 / 120 = 3.33%
in Anaphase
= 6 * 100 / 120 = 5%
in telophase
= 2 * 100 / 120 = 1.66%
The percentage of cells present in various phases exhibits the time spend by each cell in that phase.
Total minutes
= 24*60 = 1440
Total minutes spent in interphase
= 77.5 * 1440
= 1116 minutes
in prophase =12.5 *1440
= 180 minutes
in metaphase = 3.33*1440
= 48 minutes
in Anaphase = 5*1440
= 72 minutes
in telophase = 1.66*1440
= 24 minutes
Elements such as The lungs exchange gas to maintain homeostasis. In the alveoli of the lungs, oxygen and carbon dioxide are exchanged. This exchange occurs between the lungs and blood vessels (capillaries). The transport of oxygen to the blood does not require energy. The membranes of the alveoli are thin and moist and allow gasses to dissolve and be transported to and from the blood. When we breathe, a high concentration of oxygen enters the lungs and moves to the blood. Based on this scenario, is the transport of oxygen a result of osmosis, diffusion, or active transport?
Answer:
oxygen are among the few simple molecules that can cross the cell membrane by diffusion. And Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Explanation:
Answer:
This is Diffusion........... :)

Where are the instructions that control a cell's activities found?
A. DNA
B. mitochondria
C. ribosomes
Answer:
A. DNA
Explanation:
Nucleus. The nucleus, a substantial organelle that houses the cell's DNA, is referred to as the “command center” of the cell (deoxyribonucleic acid). Thus, option A is correct.
What is the main function of DNA?
The genetic information contained in the DNA is used by the nucleus to regulate all cellular functions, including growth and metabolism.
Today, DNA has three separate purposes: genetic, immunological, and structural, all of which differ greatly from one another and depend in different ways on the bases and the sugar phosphate backbone.
Genetic information is encoded in the nucleotide order along the backbone. Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Therefore, DNA which is found in nucleus control a cellular activity.

If a myostatin protein is not the right shape, it cannot fit correctly into a cells receptor true or false
Explanation: Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a myokine, a protein produced and released by myocytes that acts on muscle cells to inhibit muscle cell growth. In humans it is encoded by the MSTN gene.[6] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family.[7][8]
Therefore, if the myostatin protein is smaller than a microorganism it would be able to fit into the receptor.

How can a change in genotype affect the phenotype?
Answer:
The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.
Answer: population
Explanation: An organism's genotype is the set of genes that it carries. ... However, since an organism's genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change. For example, differences in the genotypes can produce different phenotypes.

If an acorn falls off a tree, is it living or non-living??
Answer: living
Acorns are still alive even off the tree and eventually grow into plants in the right conditions.
Answer:
Acorns are alive. Acorns live and breathe. Since they have no teeth and claws, acorns defend themselves with have chemicals called tannins. Because acorns decompose slowly, some gardeners compost them separately from other materials that break down more rapidly. Others grind them before composting them, as this speeds up decomposition.
