During the winter months, when the mountains are covered in snow, the snowshoe hare's coat is typically white. Which statement describes the genetic basis for the seasonal changes in coat color?
Answers
Answer:
a. The snow causes mutations in the genes that regulate coat color so that the snowshoe hares are adapted to their environment during the winter months.
Explanation:
:))
The snow causes mutations in the genes that regulate coat color so that the snowshoe hares are adapted to their environment during the winter month.
What is Mutation?This is defined as a change in the DNA sequence of an organism due to different factors such as exposure to radiation etc.
The snow however caused the mutation in the coat color of the snowshoe and allowing it to adapt to the environment during winter.

4. why is there difference between of nearly 2days5hours between siderial month and synodic month?
please answerr
Answers
Answer:
1.) Full moon is when the moon is fully illuminated(visible)from earth's perspective.
New Moon is the First Lunar phase.
First quarter occurs halfway between new and full moon.
Last quarter is after the full moon half of the moon is visible by the sun.
2.)
Solar eclipse where the moon is covering the sun Completely. Earth, Moon, and sun are in a straight line.
Lunar eclipse where the moon passes earth's shadow
3.)
Diamond/Graphite. Its because of the Hardness Scale of the materials. It starts at 1( the softest) Talc and 10(Hardest) Diamond. the Surface and texture and streak line also play a part in this. But Diamond is the hardest because of how much pressure it can withstand.

According to the graph, which statement best describes the effects of increasing ozone on human health?
Lung function increases when ozone gas moves above 0.1 ppm.
O Lung function decreases as ozone gas moves below zero ppm.
Lung function increases at a faster rate for older people.
Lung function decreases at a faster rate for young people.
Answers
Answer: D) Lung function decreases at a faster rate for young people.
Explanation:
Look at the slope of the graph. If you look at it the other way, you will see that it is decreasing at an extreme rate.
For young people, lung function declines more quickly. Your lung function will typically deteriorate over time as you get older, starting around the age of 35.
What role does the lung play?The process of exchanging gases, known as respiration, is the lungs' primary purpose (or breathing). During respiration, carbon dioxide, a metabolic waste product, exits the blood and oxygen from the incoming air enters. A diminished ability of the lungs to exchange gases is referred to as a lowered lung function.
How many components are there in the lungs?Summary There are lobes on each lung. Alveoli, bronchi, and the windpipe make up the bronchial tree that runs through your lungs.

How does apoptosis relate to cancer cells?
A. In cancer cells, too much apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
C. In cancer cells, apoptosis occurs only when cells grow without proper regulation.
D. In cancer cells, apoptosis occurs only when the cells receive the proper hormones.
Answers
Answer:
Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation
Many oncogenic stresses, including uncontrolled proliferation or DNA damage, trigger apoptosis; consequently, by culling cells at risk of transformation, apoptosis effectively prevents cancer. Apoptosis also suppresses tumourigenesis in various other ways.
The more malignant the tumour is, the more apoptosis shows. In this study, we propose a new theory that apoptosis plays a key role in the malignant progression and metastasis of cancer. The growth of tumour is the difference between tumour cell proliferation and attrition plus the hyperplastic growth of stroma.
What is the role of camp in the signal transduction pathway activated by epinephrine?.
Answers
Answer:
When activated, adenylyl cyclase converts a large number of ATP molecules into signaling molecules, called cyclic AMP (cAMP). Because cAMP carries the message of the first messenger (epinephrine) into the cell, cAMP is referred to as a second messenger.
Explanation:
Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.
What is cAMP?Cyclic adenosine monophosphate, often known as cyclic AMP or cAMP, is a tiny, hydrophilic molecule that functions as an essential intracellular second messenger molecule that is controlled in a variety of physiological activities.
It is now understood that cAMP regulates cellular activity in all organisms, including amoebas, plants, and people. The biological functions of memory, metabolism, gene regulation, and immunity are all mediated by this second messenger.
Therefore, Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.

Answers
Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
What is humidity?Humidity is used to determine the concentration of water vapour that is available in the air.
when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.
Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.

An atom with 9 protons and 8 electrons is what kind of atom?
Hint: Cations have more positive charges than negative charges. Anions have more negative charges than positive charges. A neutral atom has the same number of positive charges to negative charges.
A
an anion
B
a cation
C
a neutral atom
Answers
Answer:
B. A cation
Explanation:
An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.
The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).
N.B: The cation atom will have a +1 charge

Answers
ATP is a cellular energy source to do every work, ATP is synthesized during cellular respiration to use this energy for cellular processes, hence option a is correct.
How does ATP is used?During photosynthesis, it is the synthesis of ADP to ATP using solar energy. In the mitochondria of a cell, the process of cellular respiration also leads to the creation of ATP.
ATP gets hydrolyzed into ADP or AMP and produces free inorganic phosphate groups in metabolic activities. Energy-wise, the conversion of ATP to ADP is beneficial, providing a Gibbs-free energy of -7.3 cal/mol.
A series of chemical reactions referred to as cell respiration convert glucose into ATP, which may then be utilized as energy for a variety of bodily functions.
Therefore ATP is broken down into ADP and releases energy to do work for cellular processes, hence option a is correct.

• This brought about him to invite the query that 'Are the Galapagos finches and mainland finches the equal species?'
• Later on research made it glaring that some corporations of mainland finches migrated to the Galapagos island and occupied unique niches.
They adjusted themselves to the island surroundings and developed with new variations in beak shape and feeding habits.
• They at the moment are labeled into 14 corporations out of which thirteen exist withinside the Galapagos island.
