Explanation:
one of the earliest events that distinguish meiosis from mitosis occurs in prophase 1 and involves
Answer:
This question lacks options, options are:
A. Pairing of homologous chromosomes
B. Movement of chromosomes towards the metaphase plate
C. Condensation of chromosomes
D. Loss of the nuclear membrane
The correct answer is A. Pairing of homologous chromosomes
Explanation:
Mitosis and meiosis are two different forms of cell division in eukaryotic cells, those that have a nucleus.In meiosis in Prophase I: homologous chromosomes pair up and exchange genetic material by crossing over. In mitosis in Prophase I: genetic material begins to condense and form long, thin strands. The mitotic spindle is formed.During the cell cycle, the eukaryotic cell undergoes a series of changes that lead to the formation of new cells. Depending on the type of cell, it can divide by mitosis or meiosis.
Slowing signals between neurons is a function of __________. A. excitatory receptors B. excitatory neurotransmitters C. inhibitory receptors D. inhibitory neurotransmitters
Answer:
D
inhibitory neurotransmitters
Explanation:
Slowing signals between neurons is a function of inhibitory neurotransmitters. Neurotransmitters are the chemical messengers. Thus, the correct option is D.
What are inhibitory transmitters?Neurotransmitters are the chemical messengers in the body. These are released by the axon terminals of neuron and transmit the nerve impulse (message) to the neighboring cell (a muscle cell or a nerve cell).
There are primarily two types of neurotransmitters in the body, which are:
1. Excitatory neurotransmitter and 2. Inhibitory neurotransmitter
Inhibitory neurotransmitter have inhibitory effect on the neuron, they reduce the chances that a neuron will fire an action potential. They are responsible for slowing signals between neurons. Example: GABA (gamma amino butyric acid) is a common inhibitory neurotransmitter.
Therefore, the correct option is D.

Millibars are a form of atmospheric pressure.
Hurricanes or severe storms usually have very low atmospheric pressure. So your answer would be 923 HPA (Hecto pascals) or as we call it millibars. 923 Millibars is the average atmospheric pressure for a cat 4 hurricane. So charlotte with 923 is your final answer!

Describe a specific instance where an enzyme assists the human body. What role does the
enzyme play in the chemical reaction
Choose the term that best matches the description given. Treatments that destroy or decrease the growth of a microbe infection in a patient ______ a. Disinfects b. Antiseptics c. Sterilization d. Antimicrobials e. Quarantine
Answer: The correct option is D (Antimicrobials).
Explanation:
Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:
--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.
--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.
The antimicrobial drugs achieve their role usually through their different modes of action which includes:
--> cell wall inhibition
--> inhibition of cell membrane function
--> protein and nucleic acid synthesis inhibition.
Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.
describe the main difference between a bright field, compound light microscope and a dissecting microscope
Answer:
Please find the main difference in details between these two microscopes below
Explanation:
Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.
- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).
- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.

When you surprised that your mom is on the Hospital and she have a lung cancer stage4 what should you do?
Answer:
what you can
Explanation:
my grandma just got diognosed with two different types of lung cancer, stage 3. Not much you can do but be there for her. One thing that we did for her was make her a cancer/chemo basket after doing research. Apparently it tastes gross so you give them hard candy to suck on and there are certain things like ginger flavored ones or ginger smelling sticks that make you not be nasaus and hats in case she loses her hair (which they said she wouldn't) and a blanket with all of the family on it so she never has to be alone and stuff like that. They're aloud to take one bag to chemo so I would really reccommend doing it. She loved it anyway.

Answer:
movement; cell membrane; molecules; concentration; side
THIS IS know as diffusion
Explanation:
Diffusion is the movement of molecules from the side of the membrane with a higher concentration to the side of the membrane with a lower concentration. Facilitated diffusion is a process that occurs if the cell membrane is permeable to these molecules and if there exists a difference in the concentrations on the two sides of the membrane. This mechanism is also known as passive transport because no energy is needed for the movement of molecules across the membrane.

C) blue
D) yellow
Cells start to divide when they receive a signal. They continue to divide until they get another signal to stop. A cell with damaged DNA may not respond to the stop signal. The cell can become cancerous and divide uncontrollably. The cancerous cell and all its daughter cells can form a tumor. During which step of the cell cycle does a cell get a signal to begin cell division?
Answer:
Prophase.
Explanation:
Prophase is the stage of cell cycle which receive the signal to start cell division. Due to this signal, the nucleus dissolves inside the cell and the chromosomes begin movement to the middle line of the cell where these chromosomes condenses and then division of the cell occurs in later steps of mitosis cell division. So we can conclude that prophase step started when it got signal.

A man who has cystic fibrosis married a healthy women. They produce 2 children who both have cystic fiber. What are the genotypes of the man and women? (use symbols to represent the alleles and which parent is which)
Answer:
The correct answer would be -
Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
Explanation:
Cystic fibrosis is a recessive genetic disease that means it exhibits only if both copies of the gene mutated, If there is only one copy of the gene is mutated the person will be healthy however, he or she will be a carrier of the mutated gene.
Given: Father has cystic fibrosis which means he has two copies of the mutated gene - cc (c - recessive)
Female - she is healthy now there is two conditions possible
1. if the mother is healthy - CC (normal allele)
C C
c Cc Cc
c Cc Cc
All offspring are in the heterozygous condition that means they are healthy carriers which is not given in the question so women must be a carrier
2. Carrier mother - Cc
C c
c Cc cc
c Cc cc
Here 50% chances of having children with CF so it is possible as two offsprings have CF according to question
Thus, Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc

How are precipitation and temperature different between the polar and tropical climate zones?
Answer:
The temperature is colder in the polar climate zones. Also, there is less precipitation in polar climate zones. Meanwhile,the temperature is warmer in the tropical climate zones. Also, there is more precipitation in tropical climate zones.
Explanation:
The earth is extremely diverse in its ecosystem. Different regions are called climate biomes to understand patterns of meteorology, biology, and natural phenomena.
The biggest difference between tropical and polar climates is the difference in temperature. The tropical climate is close to the equator and has more sun all year round than anywhere else on the planet, but the polar climate is the furthest from the equator and has the least sunlight and heat of any part of the world. This makes winters harsher and summers shorter in polar climates, but hotter virtually every day in tropical climates. Both climates are reminiscent of precipitation (such as tropical rains and polar snow), but both can be quite dry. Antarctica is said to be the largest desert in the world because there is little snow falling towards the center of the continent.
What are examples of tropical desserts?Tropical deserts, such as the Namib Desert in Africa, are so hot and dry that it is difficult to survive.
Thus it concludes that precipitation and temperature are different between the polar and tropical climate zones.
