certain vitamins or provitamins have antioxidant properties that help protect against free radical damage to cells. check all of the following substances that have antioxidant activity.
Vitamin C, Vitamin E, and beta-carotene have antioxidant properties that help protect against free radical damage to cells.
Free radicals are unstable chemicals that the body creates in response to external and other stresses, and antioxidants are compounds that can stop or decrease the damage that free radicals do to cells. The origins of antioxidants could be either natural or synthetic, and they are sometimes referred to as "free-radical scavengers." A carotenoid is a class of chemical that includes beta-carotene. Plants that are reddish-violet in hue, such carrot, sweet potatoes, and apricots, contain carotenoids. Among provitamins is beta-carotene. It follows that your body uses it to produce vitamin A. Both vitamin C and vitamin E have antioxidant properties. Water-soluble vitamins are more easily retained in tissues because they are directly taken into the blood.

Which of the following best explains the roles plants and
animals play in recycling carbon?
a.
Plants and animals both take in carbon through
respiration. They return it to the cycle through
decomposition.
b. Plants take in carbon through photosynthesis and
decomposition. Animals produce carbon through respiration.
C. Animals produce carbon through exhaling. Plants take in
carbon for photosynthesis.
d. Plants produce carbon through photosynthesis. Animals
take in carbon for breathing.
Answer:
b
Explanation:
animals poop which feeds the ground lol
Photosynthesis and respiration recycle carbon in plants. Animals get carbon from plants and exhale it. Therefore, option (B) is correct.
What is carbon cycle?The biogeochemical process known as the carbon cycle involves the transfer of carbon between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the most common element found in organic compounds, and it also plays a significant role in the chemical makeup of numerous minerals, including limestone.
Through the process of photosynthesis, plants take in carbon from their surroundings and then release it during the process of respiration. Plants are the source of carbon for animals, and animals exhale carbon during the process of respiration.
Therefore , option (B) best explains the roles plants and animals play in recycling carbon.

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.

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.

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.
