The nervous system signals the endocrine system to release

hormones in response to a stimulus.

Explanation:

The nervous system respond to stimulus through action potentials and neurotransmitters and they signals the endocrine system to secrete hormones.

The endocrine system is responsible for secreting hormones into the blood which is transported to the target cells. These hormones are responsible for metabolism , growth and response to stress. The hormones secreted provide feedback to the brain so as to affect neural processing.

Answer:

A.

Explanation:

It converts sugars into cellular energy without requiring much oxygen, but it doesn't provide nearly as much energy as a result of the process not using oxygen.

Answer:

1. Forms fewer ATP molecules and cellular respiration

Explanation:

Alcohol fermentation is usually done by yeast as us humans lack the genetic information to do it (however we can do lactic acid fermentation in low Oxygen level which produce Lactic acid, which is what hurts after a day or two of heavy playing or workout)

Alcohol Fermentation only produces two ATP which is significantly lower than what cellular respiration makes (scientists predict there to be about 38 ATP from per cycle of respiration)

A, B

Explanation:

Sedimentary rocks are near the surface so the only one that works for that is A, sedimentary rocks are formed with water too, it weathers away at the rocks to form little sediments

Metamorphic rocks are in the earths interior and sedimentary are at the exterior, metamorphic rocks are formed through extreme heat and pressure meaning its near the earths interior

I hope this helps u!

Pls give brainliests( had 40 down to 2 no reason :(  ) and a thx ;)

Sedimentary rocks leads to the transformation of igneous rock into sedimentary rock by moving it has been exposing it to energy from sediments as uplift, upward, the Sun and subduction, downward, Earth's Interior.

Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.

Therefore, Sedimentary rocks leads to the transformation of igneous rock into sedimentary rock by moving it has been exposing it to energy from sediments as uplift, upward, the Sun and subduction, downward, Earth's Interior.

Answer:

A.

Nutrients from fertilizers on the farm wash off into the lake and cause the green slimy algal bloom

Explanation:

This question describes a team of marine biologists, who observe an inland sea covered up with a green slime. Firstly, this green slime is the the visible form of the proliferated growth of algae, hence, causing what is referred to as ALGAL BLOOM.

Algal bloom is caused by EUTROPHICATION, which is the pollution of water bodies with nutrients from fertilizers e.g phosphate, nitrate etc which causes a rapid algae growth. The excessive nutrients causing this algal bloom appearing like a green slime comes from the fertilizers used by farmers practising large scale farming within that area.

When this fertilizer is applied on plants, it gets washed into the water body and its constituents e.g phosphorus, nitrogen etc. serves as source of nutrient for the growth of marine organisms (algae). Hence, they grow excessively and form a bloom that appears like a green slime on the lake.

Hence, the farming activities is releasing pollutants in form of chemical substances which serve as nutrients for the proliferated growth of algae.

Answer:

B.  Pesticides from the farm wash off into the lake, causing algae to die

Explanation:

Green slime algae is a type of algae which is found in the marine ecosystem. This algae is a source of food for aquatic animals. It requires nutrients for producing food in the process of photosynthesis. When the nutrients present in the fertilizers such as nitrates move from the farm into the nearby lakes, its population increases and more food is available for the marine animals and fishing is not possible. But this decrease occurs in population when the pesticides wash off into the lake so farming will be possible for the fisheries.

Answer: The Byzantine Empire influenced many cultures, primarily due to its role in shaping Christian Orthodoxy.

Explanation:

Answer:

The modern-day Eastern Orthodox Church is the second largest Christian church in the world. In addition, Byzantine art from this period had a strong influence on the later painters of the Italian Renaissance.

C. Coral reef

Explanation:

Coral reefs are both found in the littoral zone which is on the shore in a tidepool and in the benthic zone which is the low level of the ocean.

The aquatic ecosystems that is likely to have both a littoral and benthic zone is lake. The correct option is a.

The benthic zone, like the ocean, is the lake floor, made up of accumulated sunken organic matter.

The littoral zone is the area adjacent to the shore where light can easily penetrate and aquatic plants thrive. The pelagic zone encompasses a large body of water.

The Benthic Zone consists of organic sediments and soil at the bottom of a pond or lake. This zone will expand as the body of water ages. It is regarded as the digestive system of a pond or lake.

The littoral zone is a pond or lake's down-sloping shelf. This is the area that extends from the high-water mark to the shore and into the area where sunlight penetrates to the sediments at the bottom of a body of water.

Thus, the correct option is a.

PLEASE MARK IT THE BRAINLIEST!

Answer:

about 525 billion sperm cells

Explanation:

In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.

Answer:

1,500

uring spermatogenesis, your testicles make several million sperm per day — about 1,500 per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm. This may seem like overkill, but you release anywhere from 20 to 300 million sperm cells in a single milliliter of semen.
