Which hormone is responsible for controlling sperm production?
Answer:
The most important hormone involved in controlling sperm production is a steroid called testosterone. This is produced in the testis itself, by the Leydig cells (see Figure 12a). The testosterone is released from the Leydig cells between the tubules, and taken up by the neighbouring Sertoli cells.
Answer:
The most important hormone involved in controlling sperm production is a steroid called testosterone.
Why is phosphorus a limiting growth factor in terrestrial ecosystems?
Answer:
Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. ... Phosphates are also limiting factors for plant-growth in marine ecosystems, because they are not very water-soluble. Animals absorb phosphates by eating plants or plant-eating animals.

#BRAINLESTPhosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.
What is the use of phosphorus in ecosystem?Phosphorus-based fertilizers boost the growth of plants on land, phosphorus in the ocean increase the production of microbes and small marine plants called phytoplankton, which compose the base of the marine food chain.
Phosphorus, like nitrogen, is a critical nutrient required for all life. The most common form of phosphorus used by biological organisms is phosphate (PO4), which plays major roles in the formation of DNA, cellular energy, and cell membranes (and plant cell walls). Phosphorus is a common component in commercial fertilizers.
We can say that phosphorus are very important factor for plant-growth in marine ecosystems because they are not soluble in water.
Therefore, Phosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.

Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration
Answer: Option C
Explanation:
The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.
Then from animals and human beings it is again transferred into the soil and then atmosphere.
The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.
What does the theory of evolution tell us about living things?
A) The environment can make them change rapidly over a short period of time. B)They create fossils when they die
C)Their environment makes them change slowly over time.
D)They can give us clues about extinct species. (science 7th grade) (100 POINTS)
Answer:
Their environment makes them change slowly over time
Explanation: I took the test and got it correct.
The agents of wethering erosion deposition and the rock cycle will slowly change the fossils over time. They may damage them or burry them deep into the layers of earth. Over time, as they age, new landforms will me made ontop of them. This is why they use the fossils to determine the age of the land. I hope this helps :)

Collagen fibrous protein
option (B)
What protein is found in connective tissue?Connective tissue that provides support and framework for the body consists of fibrous proteins and nonfibrous ground substances in varying proportions depending on their functions.
Collagen, which is the most abundant protein, constitutes about one-third of all body protein.
Do proteins provide support for connective tissues?These fibers hold connective tissues together, even during the movement of the body. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that after being stretched or compressed, it will return to its original shape.

When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

Invasive species in time destory biodiversity of an ecosystems
Explanation:
So lets go over what each answer is:
Invasive species are species that invade a ecosystem, and can harm other species and take over resources.
Populatiuons are what make up an ecosystem. There are many populations in a single ecosystem.
Biotic factors are the living things found in the world.
Abiotic factors are the opposite, being the nonliving things found in the world.
Looking at these, which would eventually destroy the biodiversity(variation of species) of an ecosystem?
This would be invasive species, for it is the only answer that harms it's ecosystem.
And this is correct, for invasive species often times can cause extiction of species, or even whole ecosystems.
For example of an invasive species, if a tree-consuming and widly reporudcing insect that lives in plains, invades a pine forest, it will eventually kill off all the trees in the area.
This wont only kill off the pine trees, but harms and could potentiallu kill the species that depend on the pine trees for survival.
Answer: invasive speices.
