Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.
Can someone please help me with this :)

Answer:
true
Explanation:
this is true, as many things that we accpet as truth are technically only theories. theories with many examples of them being true, but only theories nonetheless. for example, cell theory in biology is accepted as truth despite it being technically possible, allbeit extremely highly unlikely at this point, that we are wrong in some way about one or all of the facets of cell theory

Look at your answers to the second set of questions, “What else is made from carbon? What kinds of processes use carbon?” Now that you know more about carbon, add to your answer.
The substance which are made from Carbon include furniture, clothing etc and the kind of processes which use carbon is photosynthesis and respiration.
What is Photosynthesis?This is referred to as the process in which green plants manufacture their food through solar energy from the Sun and involves the use of compounds such as carbon dioxide and water which results in the formation of glucose.
All organic molecules contain carbon and it is found anywhere such as trees, in the form of gases etc, It is used to make variety of things such as furniture, cloth and is a very important element.
Processes such as Photosynthesis and respiration requires the use of carbon dioxide in their respective metabolic reactions which is therefore the reason why it was chosen as the correct choice.

A. crossing over
B. genetic drift
C. law of dominance
D. random segregation
E. independent assortment
Sexual reproduction promotes genetic variation. One way variation occurs is via the production of gametes during meiosis. Sexual organism are the product of sperm and egg, receiving chromosomes from both parents. But what mechanisms are at work during meiosis to promote genetic variation? Review the prompt and select all that apply
Independent assortment that promotes genetic variety is a chromosomal assortment and crossing over. Thus, options are -
(A) Crossing over
(D) Random segregation
(E) Independent assortment
What happens during meiosis?During the metaphase stage of meiosis, the chromosomes align in the center, and either the mother's or father's chromosome has an equal chance of being transferred to the daughter's cell. The bigger the number of chromosomes in a karyotype, the greater the likelihood of gamete diversity.
During meiosis, homologous chromosomes cross across, allowing DNA fragments to be exchanged between sister chromatids. This results in variation.
Thus,
(A) Crossing over occurs when homologous chromosomes join up with non-identical twins and swap DNA sections.
(D) The distribution of chromosomes among four gametes is known as random segregation.
(E) Independent assortment entails the separation of a pair's homologous chromosomes into distinct gametes.

10. shields cl, dalvin la, lim ls, et al. circumscribed choroidal hemangioma: visual outcome in the pre-photodynamic therapy (pdt) vs pdt eras in 458 cases. retina. in press. 2019.
Purpose
To investigate features and outcomes of circumscribed choroidal hemangioma by patient age.
Methods
Retrospective review of circumscribed choroidal hemangioma from 3/29/1967–6/4/2018 based on age at presentation (≤20 vs. >20–50 vs. >50 years).
Results
There had been 458 circumscribed choroidal hemangiomas diagnosed at mean age (13 vs. forty one vs. 64 years, p < 0.001). The youngest age crew had worse offering visible acuity (20/400 vs. 20/150 vs. 20/100, p < 0.001), larger tumor basal diameter (13.5 vs. 6.6 vs. 6.2, p < 0.001), greater tumor thickness (5.8 vs. 3.1 vs. 2.9, p < 0.001), closer distance to foveola (0.5 vs. 1.4 vs. 1.2, p = 0.03), and larger extent of subretinal fluid (4 quadrants, 26% vs. 8% vs. 2%, p < 0.001). The youngest sufferers have been much less likely to be treated with important remark (39% vs. 39% vs. 56%) or photodynamic therapy (10% vs. 27% vs. 22%) and extra probably to be dealt with with plaque radiotherapy (26% vs. 6% vs. 3%) or exterior beam radiotherapy (13% vs. 1% vs. 0%) (p < 0.001). The youngest sufferers required higher total range of redress (mean 4 vs. 2 vs. 1, p < 0.001). At mean follow-up (44 vs. 68 vs. 60 months, p = 0.37), the youngest patients had worse visible acuity (20/400 vs. 20/200 vs. 20/100, p = 0.03), however no distinction in visible acuity loss of 3 or extra Snellen lines (27% vs. 13% vs. 16%, p = 0.55).
Conclusion
Younger patients (≤20 years) with circumscribed choroidal hemangioma existing with worse visible acuity and larger, greater posterior tumors. Future studies are wanted to improve early detection and cure for this subgroup of patients.
A hemangioma is a shiny purple birthmark that shows up at beginning or in the first or 2nd week of life. It appears like a rubbery bump and is made up of more blood vessels in the skin. A hemangioma can manifest anywhere on the body, but most generally appears on the face, scalp, chest or again .

Option C: The peritoneum is the lining of the abdominal cavity and some of its organs.
The Peritoneum is a membrane of a sheet of smooth tissue that lines the inside of the abdominopelvic cavity and surrounds the abdominal organs. It also covers many other organs inside the visceral layer. It acts as a pad and insulates the organs, helps them to hold them in place, and secretes a lubricating fluid to reduce friction when they rub against each other. The space between the layers is called the peritoneal cavity. The folds of tissue form double layers, which hang down the front of the abdomen, and mesentery in the back.
