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.

status, trends, and equilibrium abundance estimates of the translocated sea otter population in washington state
Prior to their local extinction in the early 1900s as a result of the marine fur trade, sea otters (Enhydra lutris kenyoni) once lived in Washington State, USA.
After being extinct, 59 sea otters were brought from Amchitka Island in Alaska, USA, to the coast of Washington. Of these, 29 were released in 1969 at Point Grenville and 30 in 1970 at La Push.
Estimates of the translocated sea otter population's status, trends, and equilibrium abundance in Washington StateA chosen sample level and a target geographic distribution are the two key goals set forth by the Washington Department of Fish and Wildlife for the recovery of sea otters. Estimations of these characteristics have significant management consequences because recovery requirements are dependent on estimates of populations abundance, equilibrium abundance, and geographic distribution. In order to assess history and present abundance as well as equilibrium abundance at various spatial scales, we collated all survey data for sea otters that have been recorded in Washington State since their relocation (1977–2019). As a foundation for a sensitivity analysis to gauge the relative impact of movement behavior, in Journal of Wildlife Management, we then utilized forward predictions of population dynamics to investigate different scenarios of range recolonization.learn more about sea otters here

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 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.

During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. True or false?.
The given statement is true. During glycolysis, a 6-carbon sugar diphosphate that is fructose-1,6-bisphosphate is splitted into two 3 carbon sugar phosphate molecules that are dihydroxyacetone phosphate and glyceraldehyde-3-phosphate.
What is glycolysis?Glycolysis is a 10-step reaction wherein glucose is divided into two pyruvate molecules, each of which has three carbons.
Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms also contain this route since glycolysis does not require oxygen.
What are the various steps involved in glycolysis?1. The conversion of D-glucose into glucose-6-phosphate is the initial step in the glycolysis process. The enzyme catalyst in this case is hexokinase.
2.This second phase involves the conversion of fructose 6-phosphate from glucose 6-phosphate.
3. Using magnesium as a cofactor, fructose 6-phosphate is changed into fructose 1,6-bisphosphate.
4. Fructose 1, 6-bisphosphate is split into two identical sugars by the enzyme aldolase. Dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate are the names of these two sugars.
5.The molecules glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP) are quickly interconverted by the enzyme triphosphate isomerase.
The first five steps listed above are regarded as the initial phase.
.Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) converts glyceraldehyde 3-phosphate into 1,3-bisphosphoglycerate by dehydrating it and adding an inorganic phosphate.
7. To create ATP and 3-phosphoglycerate, a phosphate group from 1,3-bisphosphoglycerate is transferred to ADP.
8. In this step, Phosphorous from 3-phosphoglycerate is transferred from the third carbon to the second carbon to generate 2-phosphoglycerate.
9. An enzyme removes a water molecule from 2-phosphoglycerate to create phosphoenolpyruvic acid (PEP).
10. Phosphoenol pyruvic acid is converted to pyruvate.

: The given statement is True.
A 6-carbon sugar molecule is divided during glycolysis into two 3-carbon sugar molecules. Glucose, a 6-carbon sugar molecule, is also known as a hexose sugar. 3-phosphoglycerate refers to the 3-carbon sugar molecules created during glycolysis. Cells use the process of glycolysis to break down glucose and produce ATP as a source of energy (adenosine triphosphate). There is no need for oxygen because the process takes place in the cytosol of cells (anaerobic). All cells use the same pathway to produce energy, and it is the first stage in the breakdown of glucose to do so.

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.
