A scientist discovers a new species of marine bacteria that do not require oxygen to survive. In fact, dissolved oxygen in the w

ater is actually toxic to these bacteria. Predict what region of the ocean this species would most likely inhabit, and select the best explanation.
A.)Deep becasue there is less oxygen exchange
B.)Deep because there are more oxygen-containing compounds
C.)Shallow because more oxygen is produced
D.)Shallow becasue low pressure increases dissolved gas

Answer - A. Deep because there is less O2 exchange

Reasoning - Bacteria has been known to only use half a percentage which is .5 percent of O2.

Answer:

Option (A).

Explanation:

Bacteria are involved in the prokaryotic organisms as well as in the Archean. Bacteria are unicellular organism that generally reproduces by the asexual reproduction.

A new bacteria has discovered that does not require oxygen for their survival and oxygen acts as a toxic substance for these bacteria. The bacteria is generally found in the deeper zone as the oxygen exchange is less in this area.

Thus, the correct answer is option (A).

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

Zinaida [17]
The answer is letter C.
<span>
The interdependence of body systems is essential because all systems work together to maintain homeostasis. Homeostasis in body systems refers the regulation of internal conditions keeping it stable and relatively constant. In humans this refers to its ability to maintain stability in its internal environment while responding to changes in external conditions. It serves as a sensor that detects changes in the conditions that need to be regulated to meet the demands of the condition and give the necessary feedback. Regulation of body temperature and the balance between acidity and alkalinity are examples of homeostasis in the human body.</span>

In 1997, Dolly the sheep was cloned. Which of the following processes was used?
allsm [11]

Answer:

Option (D).

Explanation:

Dolly was the first sheep cloned in the year 1997. The sheep has been cloned from the adult somatic cells. The sheep was cloned by  Keith Campbell, Ian Wilmut.

The adult's cell nucleus was fused with the enucleated sheep egg. The egg was then incubated in the surrogate female. The telomeres of Dolly sheep was found to be shorter than the normal individuals.

Thus, the correct answer is option (D).
