The cell membrane of the red blood cell will allow water, oxygen, carbon dioxide, and glucose to enter and leave the membrane. Why is this function of the cell membrane important?
Answer:
All substances that the cell needs(such as water and other nutrients) enter through the cell membrane. Waste products of the cell come out through the cell membrane. The cell membrane prevents harmful substances from entering the cell and keeps useful substances inside the cell.

What percent of America's original forest remains today?
Less than 4% or under 40 million acres of America's original forests remain in existence.
(hope this helps ^^)
Answer:
Less than 4% or under 40 million acres of America's original forests remain in existence. According to the World Resources Institute, less than 1% of "Frontier Forests"--large, contiguous virgin forests with all the species intact--still exist in the lower 48 states.

What is the process the does not require oxygen?
Electron Transport Chain
Fermentation
Krebs Cycle
None of the above, they all need oxygen
Answer:
The process that does not require oxygen is fermentation.
Explanation:
Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.
The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.
With respect to the other options:
The electron transport chain and the Krebs cycle occur in the presence of oxygen.Fermentation is an alternative route for obtaining energy, in the absence of oxygen. Fermentation is the process that does not require oxygen.

When a germ cell undergoes meiosis, which event would MOST likely result in four aneuploid daughter
cells?
A. misalignment of the chromosomes during metaphase I
B. misalignment of the chromosomes during anaphase I
C. misalignment of the chromosomes during metaphase II
D. misalignment of the chromosomes during anaphase II
Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.

A. misalignment of the chromosomes during metaphase I

If organisms are energy deprived (ie given no food, nutrients or light) indoors at 23°C for 24 hours and they
lose mass, what is the m t likely explanation of reduction in mass over those 24 hours?
o Cellular respiration
O Water loss due to evaporation
O Growth and reproduction
The law of conservation of matter
Answer:
Cellular respiration
Explanation:
The likely explanation for this reduction in mass is due to cellular respiration going on within the cell.
Cellular respiration is a metabolic process in which food materials are broken down to produce energy. This is catabolism. The food materials contributes significant weight to the body system of an organism When the food reserve is depleted, weight loss ensues. Cellular respiration will therefore proceed and the food reserve is being depleted. This will eventually lead to loss of weightIf you’re going hiking this weekend and you have the option of hiking a mountain (A) that is 1400 meters in height and a mountain (B) that is 650 meters in height, BUT you know that you have limited time because of other plans – which mountain would you choose to hike? Why?
Answer:
I would choose mountain B cause it's only 650 meters short from mountain A (1400 meters )
Explanation:
short the length less the time we take to cover .
so we will complete our hiking soon. we will get time to do other things .. so it will be best to hike on mountain B

Explain how independent assortment occurs in cells and explain its importance
Answer:
Independent Assortment is the second law of inheritance
Traits are passed from parents to offspring independently of one another.
Independent assortment is random and occurs during Metaphase I of meiosis.
There are two possible alignments for the chromosomes.
Since the alignments are random and not assigned, genetic variation occurs.

The nondisjunction in the first mitosis that causes a fly gynandomorph to form could only occur in a zygote that is:_________A. XYY
B. XO
C. XY
D. XX
Answer:
A. XYY
Explanation:
Nondisjunction: The term "nondisjunction" is described as the failure of "sister chromatids" or "homologous chromosomes" to separate properly or precisely during cell division.
Gynandromorphism hasn't been discovered or identified in human beings, but it has been expressed or found in a variety of other creatures. However, a few scientists believe that gynandromorphs are considered as chimeras.
Example: In insects, the given condition can be caused due to the fact that two distinct sperm enters in one egg.
