c) Comprise the microbial population known as phy
d) Form active feeding forms called trophozoites
Answer:
c) Comprise the microbial population known as phyDoes every gene combination show up in the offspring?
Answer:
Answer!
Explanation:
Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.
Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.
Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

the energy role responsible for capturing the energy from the sun and turning it into food is a
A. producer
B. Consumer
C. Decomposer
Answer:
A. Producer
Explanation:
The primary source of energy for almost every ecosystem on Earth is the sun. Primary producers use energy from the sun to produce their own food
Answer:
Hi, there the answer is A. producer
Explanation:
All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

When blood passes through a capillary bed in the
it downloards O2 and uploads CO2.
Answer:
Exchange of gases takes place at alveoli sacs of lungs, which are equipped with capillary vessels or bed.
Explanation:
On inspiration or taking air through nostrils, surrounding air enters the lungs and it reaches air sacs or alveoli. Here, the outside air will have more amount of oxygen when compared with oxygen in blood at that site. Hemoglobin in the blood have high bonding capability to oxygen, so it captures oxygen and takes it to heart for pumping into other parts of the body. Likewise, the circulations continues from lungs to heart > hear to body parts > body parts to heart > heart to lungs for purification.

Where does wind come from? Why and how is wind stronger than other times? Or why and how is wind lighter ( not as strong) as other times.
Answer:
Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.
Strong winds are due to a strong pressure gradient force. A pressure gradient is how fast pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.
Explanation:
A small proportion of humans have resistance to strains of HIV, the virus that causes AIDS. Their immunity is caused by a deletion in gene CCR5, a co-receptor on white blood cells needed for HIV infection. The proportion of people with resistance (genotype aa) to HIV is approximately 8%. If these alleles are in Hardy Weinberg equilibrium, what proportion of people are carriers for the HIV resistant allele?
Answer:
The correct answer is "40.6%". A further explanation is provided below.
Explanation:
The given values are:
The proportion of people with resistance is,
aa = 8%
or,
= 0.08 (q²)
q² = 0.08
q = √0.08
= 0.28284
Now,
⇒ [tex]p+q=1[/tex]
⇒ [tex]p=1-q[/tex]
[tex]=1-0.28284[/tex]
[tex]=0.717157[/tex]
hence,
For the HIV resistant allele, the proportion of people will be:
= [tex]Aa[/tex]
= [tex]2pq[/tex]
On substituting the values, we get
= [tex]2\times 0.71715\times 0.28284[/tex]
= [tex]0.4056[/tex]
= [tex]40.6[/tex] (%)
The proportion of the population with the carrier of HIV-resistant allele is 40.56%.
What is Hardy Weinberg equilibrium?
Hardy Weinberg equilibrium is the relationship between the variation from one generation to the next. The equation for the relationship can be given as:
[tex]p^2+2pq+q^2=1[/tex]
Where the proportion of dominant alleles is p².
The proportion of recessive alleles is q².
The proportion with the caries are 2pq.
The given recessive allele proportion in the population is 0.08. The proportion of dominant alleles can be given as:
[tex]q^2=0.08\\q=0.2828[/tex]
The dominant alleles can be given as:
[tex]p+q=1\\p+0.28284=1\\p=0.717157[/tex]
The carriers in the population can be given as:
[tex]\text{Carriers}=2pq\\\text{Carriers}=2\;\times\;0.717157\;\times\;0.2828\\\text{Carriers}=0.4056\\\text{Carriers}=40.56\%[/tex]
Thus, the carriers for the HIV gene in the population are 40.56%.

Explanation:
Under normal cellular conditions, the FoF1 complex of the inner mitochondrial membrane functions to create new ATP. Under non-physiologic experimental conditions, isolated FoF1 complex can be driven in reverse as long as [ATP] is high. Which of the following would be true under such conditions?
A. The FoF1 complex would be operating as an ATPase rather than an ATP synthase.
B. The FoF1 complex would be driving net H+ movement from the matrix side to the IMS (intermembrane space) side
C. The FoF1 complex would create more ATP, per unit time, than it does under physiological conditions
D. As the experiment continues, we would expect to see higher & higher concentrations of ADP.
E. The FoF1 complex would effectively be operating as a proton pump.
Answer:
The answer is "Option A, B, and E".
Explanation:
In specific cell conditions, the F0F1 system of the inner mitochondrial membrane functions as an ATP synthase for generating new ATP ADP proteins and Pi. Even so, this has a specific biological role in non-physiological situations through functioning as an ATPase. Its ATPase acts in such circumstances and transmits large amounts of ATP to both the mitochondrial space throughout the transmembrane proton gradient.
The free radical of the transmembrane can be used by fermenting bacteria without an electron transport system. Its ATPase is being used to generate a proton gradient rather than to hydrolyze ATP. It may be used as a means of transporting flagella or nutrients into its cell.
The statements which are true about the FoF1 complex are:
The FoF1 complex would be operating as an ATPase rather than an ATP synthase.The FoF1 complex would be driving net H+ movement from the matrix side to the IMS (intermembrane space). The FoF1 complex would effectively be operating as a proton pump.So, the correct options are A, B, and E.
What do you mean by FoF1 complex?This complex is present in bacterial and mitochondrial H(+)-ATP synthases both consist of a membranous sector, Fo, which forms an H(+)-channel, and an extramembranous sector, F1, which is responsible for catalysis.
This FoF1 complex is the site of ATP synthesis along with the movement of protons (H+) from the matrix to the IMS. It is effectively operating as a proton pump because it mediates the transport of H+ ions out of the matrix.
Therefore, statements A, B, and E are correct with respect to the FoF1 complex.
