Plz answer I will mark u as brainly. Carla drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis. Which label belongs in the area marked Y? Enters plant as a part of water Combines with carbon dioxide Is released into air through stomata Is stored in leaves for later use

Answers

Answer:

Option A, Enters plant as part of water

Explanation:

In the process of photosynthesis, water molecule is broken down into oxygen and hydrogen through photolysis.

Once the molecule is broken down , oxygen is  released and hydrogen ion are used for initiating the further reactions in photosynthesis.

The following reaction occurs in photolysis-

2H2O -----> 4H+ + O2

Water is the most suitable subset among all.

Hence, option A is correct

Answer:

Not sure, but a good chance that it is released into air through stomata

Substances that are altered by the action of proteases are
known as
1) substrates
2)lipids
3)polysaccharides
4) phosphates

Answers

Answer:

Substances that are altered by the action of proteases are known as: 1) substrates.

Explanation:

Protease is an enzyme, therefore a substrate would have to fit the enzyme, which forms an enzyme-substrate complex. This causes a chemical reaction since enzymes are biological catalysts. Many enzymes often change their shape so that the substrate can fit at the active site.

Answers

Answer:

yeah

Explanation:

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.

Alternative names for thyroxine

T4; tetraiodothyronine; thyroxin

What is thyroxine?

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys. Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.

How is thyroxine controlled?

The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.

This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body.

What happens if I have too much thyroxine?

The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This may be caused by overactivity of the thyroid gland (hyperthyroidism), as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre, which is a swelling of the neck due to enlargement of the thyroid gland. Other symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, irregular menstrual cycle, rapid or irregular heartbeat, palpitations, tiredness, irritability, tremor, hair

How does the fact that infants raised on breast milk were nine times less susceptible than bottlefed infants to lymphoma demonstrate that there may be a link between something in human milk and cancer-cell destruction?

True.

Explanation:

The fact is true that the human milk helps in the destruction of cancers due to presence of Human Alpha-lactalbumin.

Answers

Answer:

Advantages

•  After the procedure, the female will no longer have to worry about becoming pregnant again.

•  It causes no hormonal changes to the body.

Disadvantages

•  The procedure is difficult to reverse. So even if there is a slight chance that you might consider having children in the future, this procedure is not meant for you.

•  Tubal ligation does not offer any protection against sexually transmitted diseases.

•  If in case the procedure fails and you become pregnant, you have an increased risk of ectopic pregnancy. Ectopic pregnancy is the one where the foetus develops outside the uterus.

•  Any kind of surgery is prone to complications and the same applies to mini-laparotomy as well. The surgery might result in some or any kind of infection, bleeding, injury to the bowels, bladder, or uterus. It may also result in permanent scarring.

the impact of extinction to the environment

Answers

Answer:

Changing systems are inevitable but likewise bring harsh and even uncontrollable effectsExtinction is especially harmful because of the concept of mutual or coexistence theorems in which certain animals depend on others We will examine the food chain: Say that grasshoppers go extinct and the lizards that eat them exclusively now have no food source. That effect transcends into a higher order as it climbs up the food ladder. Effectively these said lizards could have been controlling the bug population and effectively the grasshoppers controlled smaller micro organisms which now are left to their own devices given the extinction of the grasshoppers.effectively those microorganism can damage ecosystems and dramatically change the composition or animals and vegetation that exist in said area.

Answer:

1) it'll affect the chain reactions in the whole ecosystem and therefore, have a big effect on the environment.

2) if this happens then humans may lose the source of medicines as well, thus humans will be hit by a disease and there would probably be no cure, hence again affecting the biodiversity.

Other Questions
Revise this to make it more persuasive and formalMany cities and towns have community gardens--places the city council sets aside for people to rent garden space and plant a few veggies or flowers. The question, though, is whether they are totally useless or not. To evaluate this, it is important to look at how much time and how much money are needed to set the garden up, what it takes to maintain the gardens, and whether people use them and benefit from them. When you look at the big picture, community gardens in most large cities are awesome. However, as someone who visits the community garden in my small town every now and then, let me tell you, it is pricey, dicey, and seedy but not in a good way, a real waste of space.Usually, city gardens need to be built from scratch. That means cities must buy and haul in all the materials for the garden beds. If these are raised beds. They must buy bricks or lumber. Sometimes organizers of community gardens will get lucky. Someone will donate materials to them. They still must have it moved on-site, though. Also, many community gardens require loads and loads of dirt and fertilizer, plus, an irrigation system. It takes a lot to make a garden from zilch. The costs can far outweigh the benefits in small communities. Larger cities can make this work. They have more options for materials. They also have more people using the completed garden.The next important thing to look at is how the community keeps up the garden. Often community gardens require their renters to spend a certain amount of time weeding and watering the garden. While this might sound good in theory, my experience is that people rarely follow through. They usually start out doing a bang-up job in the spring during planting time, but then their lives get more and more swamped, so they disregard this commitment. If a city is large enough to have someone on site. Maintenance is not as big of a deal. However, in my small community garden, no one is ever around. In fact, weeds are the reigning vegetable growing in our community garden. This makes our town's community garden a waste of time.Thanks, Weirdo12345 The California Mussel ( Mytilus californianus ) is the natural prey of the shore crab ( Carcinus maenas ).
