D.carbon dioxide
Answer:
B.Sugar ( Glucose)
Explanation:
I hope this helps!
A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.
The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.
The reaction of photosynthesis is given below:
[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]
Therefore, a compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

How can one system be consider a component of another system?
Answer: The body is a system filled with smaller systems. Each used to help out the other and benefit the body as a whole. For example, the respiratory system takes in oxygen, the heart then takes the oxygen in the blood and pumps it throughout the entire body. Then veins carry that blood to muscles and organs. Each unique system has a job to do, when one malfunctions the whole system can fail.

X^r X^r and X^r Y genotypes of people who have the disorder.
What are genotypes?A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
Moreover, the different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
Hence, there are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.

(d) Cells are treated with a compound that prevents the inactivation of kinase D . Researchers claim that Brec-WT cells treated with this compound will stimulate blood vessel-forming cell division to the same degree as Brec-MUT cells do in the absence of B . Based on the information provided, provide reasoning to support their claim.
Answer:
There are two kinds of communication in the world of living cells. Communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling. An easy way to remember the distinction is by understanding the Latin origin of the prefixes: inter– means “between” (for example, intersecting lines are those that cross each other) and intra– means “inside” (like intravenous). Chemical sign
Explanation:
As per the details provided, the correct reasoning to back the given claim would be as follows:
- Both cell types have active kinase D, which leads to the expression of A, and the expression of A stimulates the blood vessel-forming cell division by both cell types.
The correct reasoning to back the given claim that cells are intentionally handled using a compound that avoids the kinase's upregulation would be as mentioned above. In the given example, the use of Brec-WT cells shows that both the given cells contain kinase D in their activated form that causes the appearance of A. This appearance further results in the incitement of blood vessels which causes the division of cells through both kinds of cells.Learn more about "Cell" here:

Two populations live in the same habitat and compete for food. The first group is larger and multiplies through asexual reproduction; the second reproduces sexually. What could happen to cause the second group to outnumber the first?
Answer:
an environmental change that causes the larger but unadaptable species to die off
Explanation:
Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.
What happen when the process of meiosis does not takes place?If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.
The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has formed which gives rise to the organism having diploid cells.
Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

The Lac Operon is a set of genes that controls the production of lactase the enzyme that digests
lactose. In the top picture: The gene is "turned off" resulting in no mRNA being made. In the
bottom picture: The gene is "turned on" allowing the RNA polymerase express the genes,
resulting in production of the lactase enzyme.
which statement is not correct about the lac operon?
Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.

contractions.
Answer:
The correct answer is - Peristalsis
Explanation:
Boluses of the food move through involuntary movements of circular and longitudinal muscles known as Peristalsis is, mainly in the digestive tract or alimentary canal. These movements are likes waves or contraction in the alimentary canal.
In the oesophagus, the movement of this series of movements known as peristalsis starts from the top portion of the tube and pushes the food and pushed it into the stomach.

Which does NOT describe acid precipitation?
Multiple choice question.
A)
It increases when air pollution levels are low.
B)
It decreases the pH of lakes and other bodies of water.
C)
It can form when moisture combines with sulfur dioxide from power plants.
D)
It can be rain or snow.
Answer:
c
Explanation:
the moisture that has the sulfur will go through evaporation and then rain
"It can form when moisture combines with sulfur dioxide from power plants" is not observed in acid precipitation, hence option C is correct
One of the effects of air pollution is acid rain. Fuel combustion generates gases that combine with oxygen in the air and water vapor to create acids that eventually fall as rain on the earth's surface.
Any type of precipitation with high concentrations of nitric and sulfuric acids is referred to as acid rain. Snow, fog, and little pieces of dry material that fall to Earth can likewise represent it. Acid rain typically has a pH between 4.2 and 4.4, whereas normal rain has a slightly acidic pH of 5.6.
