why genetic factor is very important in crop production
Answer:
The wise use of crop genetic diversity in developing improved crops can contribute significantly to protecting the environment. Crop varieties that are resistant to pests and diseases can reduce the need to apply harmful pesticides. More vigorous varieties can better compete with weeds, reducing the need for applying herbicides .
Explanation:
Li-Fraumeni syndrome (LFS1) is a rare hereditary disorder that leads to a predisposition to cancer. This hereditary disorder is linked to mutations in the tumor suppressor gene encoding the transcription factor p53. p53 acts at the G1 checkpoint. If damaged DNA is detected, p53 halts the cell cycle. As p53 levels rise, the production of p21 is triggered. p21 enforces the halt in the cell cycle. A variant of Li-Fraumeni, called LFS2, is thought to occur due to a mutation of the CHK2 gene, which is also a tumor suppressor gene. CHK2 regulates the action of p53. Which of the following cascades is most likely to occur in a normal cell that does not contain the LFS mutation?
Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

which part of the carbon cycle breaks down carbohydrates into carbon dioxide and water
Resipration
Ersion
Decomposition
Answer:
Respiration
Explanation:
Respiration is a component of the carbon cycle which breaks down carbohydrates into carbon dioxide and water.
Respiration is an aerobic process that takes place in the presence of oxygen.
It is a catabolic process in which energy rich compounds are broken down. In this process, oxygen combines with carbohydrates to produce carbon dioxide and water with the release of energy. Carbohydrates is rich and embedded with energy.Cellular respiration is the process that releases energy for living organisms.

Which letter is on the steepest slope?
(A.) A
(B.) B
(C.) C
Answer:
Letter B is on the steepest slope.
Explanation:
A is not correct because letter A is on a position where the contour lines are not close to each other, suggesting that the slope is not mild.
B is correct because the spacing between the contour lines where the letter B is marked is very small, suggesting that the slope is very steep.
wC is not correct because just like with letter A, the contour lines are not close to each other, but are further away, suggesting that the slope is not steep but it is mild.

D. Amino Acids
Answer: A carbohydrate is a simple sugar. Its basic structure is composed of the elements carbon, hydrogen and oxygen, with generally twice the hydrogen as carbon and oxygen. In its simplest form, a carbohydrate is a chain of sugar molecules called monosaccharides.
Explanation:
In which of these compounds are there twice as many oxygen atoms as hydrogen atoms
Answer:
[tex] H_2SO_4 [/tex]
Explanation:
In the first option, the compound [tex] HClO_3 [/tex] has 1 hydrogen atom and 3 Oxygen atoms. There are 3 times as many oxygen atoms as hydrogen atoms.
In the second option, the compound [tex] H_2SO_4 [/tex] has 2 hydrogen atom and 4 Oxygen atoms. That is 2:4 = 1:2. Therefore, there are twice as many oxygen atoms as hydrogen atoms.
In the third option, the compound [tex] H_2O [/tex] has 2 hydrogen atoms and 1 Oxygen atom. There are ½ times as many oxygen atoms as hydrogen atoms.
In the fourth option, the compound [tex] H_3PO_4 [/tex] has 3 hydrogen atoms and 4 Oxygen atoms. 4 oxygen atoms to 3 hydrogen atoms.

Certain bacteria change nitrogen gas into a usable form in a process called
Certain bacteria change nitrogen gas into a usable form in a process called nitrogen fixation.
What is nitrogen fixation?Nitrogen fixation process is important for the growth of plants, as nitrogen is an essential component of many plant nutrients. Nitrogen fixation is primarily carried out by bacteria in the genus Rhizobia, which form symbiotic relationships with certain plants, such as legumes. The bacteria live in nodules on the roots of these plants and convert atmospheric nitrogen into a form that can be used by the plant.
This process is also important for the overall health of the soil, as it helps to increase the availability of nitrogen for other organisms in the ecosystem.

Which of these is a distinguishing characteristic between the domains Bacteria and Archaea?
Answer:
This question lacks options, the options are:
a. Their size
b. The chemical composition of the cell wall and cell membrane
c. Their ability to grow at high temperatures
d. The shape of their mitochondria
The answer is B
Explanation:
Living organisms has been classified into three domains namely; Eukarya, Archaea, and Bacteria. However, domians Archaea and Bacteria are most similar in the sense that they both have cells without a membrane-bound nucleus, hence, they are both PROKARYOTIC. Also, they are both strictly unicellular organisms.
Despite these similarities, differences exists between them. One major difference is in the chemical composition of the cell wall and cell membrane. The cell walls of bacteria cells have a unique structure called PEPTIDOGLYCAN. This is absent in the Archeae group. Also, the cell membrane of Archeae is made up of ether linked lipids compared to the ester-linked lipids that constitutes bacteria cell
Which type of cell have membrane bound organelles?
prokaryotes
Or
eukaryotes
Answer:
eukaryotes
Explanation:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.
What is eukaryotic cell?The eukaryotic cell is known as the fully developed and it contain membrane bound organelle. The multicellular organism are made up of the eukaryotic cell and they contain cell organelle it contain mitochondria, ribosomes, RNA, DNA, golgi appratus, and nucleus as well as other cell organelles.
Multicellular organisms are made up of eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
Amoeba has known as an unicellular organism in which all the activities related to life carried out in a single cell. The example of multicellular organism is human beings and other animals as well plants are also came in the category of multicellular.
Therefore, Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.

Homeostasis Review - List some things in living things that need to be regulated
Answer:
Homeostasis The tendency to resist change in order to maintain a stable, relatively constant internal environment
Explanation:
The body maintains homeostasis for many factors. Some of these include body temperature, blood glucose, and various pH levels.
Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.
Feedback loops
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values. An example of a negative feedback loop is body temperature regulation.
Example of negative feedback loop
Example of negative feedback loop
The maintaining of body temperature is an example of a negative feedback loop. When body temperature increases, there are mechanisms that work to decrease temperature, and vice versa.
In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
Example of positive feedback loop
Negative feedback loop=
Feedback loop that acts to oppose the triggering stimulus
Positive feedback loop= Feedback loop that amplifies the starting signal
