The outer layer of the onion cell contains cellulose as compared to the skin cell, hence option B is correct.
What is cellulose?3,000 or more glucose molecules make up the complex carbohydrate or polysaccharide known as cellulose.
The most prevalent of all naturally occurring organic substances, cellulose is the fundamental structural element of plant cell walls and makes up about 33% of all vegetable matter (it makes up 90% of cotton and 50% of wood).
The majority of all naturally occurring organic materials are composed of cellulose, which makes up roughly 33%, 50%, and 90% of all vegetative plants, cotton, and wood, accordingly.
Therefore, it decides the shape of the plant and enables the plant to grow upright, cellulose gives plant cells their stiffness, hence option B is correct.

A population of drosophila flies lives in a forest and has variation in their egg-laying behavior. The majority of the flies have the trait of laying eggs in the rotting bark of trees. A small percentage of the flies have the trait of laying eggs in bark that is dampened by sap. The drosophila population moves into a new forested area that is drier, where rotting bark is harder to find than sap. How will the population change over several generations
Answer:
It will contain a larger proportion of flies that lay eggs in sap because the trait results in a higher chance of reproducing successfully and passing on the gene
Explanation:
Over the years the population of flies that lays egg in the rotten bark will reduce this is because of the low chance of reproducing and there will be an increase in the population of flies that lays egg in the sap because the flies have a higher chance of reproducing successfully leading to an increase in the population and the ability of the gene to be passed on successfully to their offspring in next generation.

Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.
a. 1,3,6,8,9.
b. 2,3,5,8,9.
c. 1,4,6,7,10.
d. 2.4,5,8,10.
e. 2.4.5.7.9.
Answer:
The answer is "Choice e".
Explanation:
The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.
Over time, how will the distribution of matter in a galaxy cluster change?
Answer:
Galaxies are in clusters and over time those clusters will join and make more, and soon they will part into their own and probably join a different one. That may sound a little confusing to some but it's quite simple. My mom explained it to me like friends, you meet some people and become friends and then sometimes you will drift away and make new friends.

According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food select all that apply
Answer:
It provides ATP.
Explanation:
It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.

1, name the part of the reproductive system in which fertilisation happens.
2, what is an embryo
3, where does the embryo develop into a foetus, and then a baby
4, why does the uterus lining start to grow thick and spongy, as an egg cell develops in an ovary
5, what happens to the uterus lining if the egg cell is not fertilised
6, how often does an egg cell leave an ovary, in an adult woman
7, how often does menstruation happen, in an adult woman
Answer:
°•°
Explanation:
1.fallopian tube
2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)
3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.
5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month
7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

With the land upon which they have built their homes slowly melting and sinking, they have appealed to the state and federal governments for assistance in helping them cover the costs of moving their town to a different location. Ironically,
A) the land upon which the Alaskan state government buildings are located is also melting.

E) the economic activity of the town of Newtok is extremely polluting and thus a big contributor to the environmental changes that have turned its residents into the first climate change refugees in the United States.
Answer:
The correct answer is D)
Decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.
Explanation:
Sedentism is simply the practice of settling in one geographical location for a long time.
Many governments encourage this to ensure that agricultural systems become developed and more sustainable as was the case in Alaska.
Other governments in some part of the world are also in support albeit for a different reason such as security of lives and property.

From fossil evidence, you know two species shared a common ancestor approximately 50 million years ago. In comparing a known neutral sequence between rats and mouse, you found 92 base differences in 1000bp. From this information, which of the following values is closest to what you would predict the mutation rate to be?
a. 1 x 10-9
b. 4 x 10-9
c. 2 x 10-9
d. 5 x 10-9
e. 5 x 10-8
f. 8 x 10-9
Answer:
Option c ([tex]2\times 10^{-9}[/tex]) is the correct alternative.
Explanation:
Given:
Common ancestor,
= 50 million years ago
Base differences,
= 92
Now,
The predicted mutation rate will be:
= [tex]\frac{92}{50\times 10^6\times 1000}[/tex]
= [tex]\frac{1.84}{10^9}[/tex]
= [tex]1.84\times 10^{-9}[/tex]
or,
= [tex]2\times 10^{-9}[/tex]
Thus the above solution is the right one.
