This is a form of sexual reproduction. The male sperm joins with the female egg. This is called fertilization. After the sperm and the egg join, it creates a zygote, that then develops and becomes an organism. After that, you know what happens. lol

I hope this helped. Comment below if it did. Brainliest would be great.

Of the answer choices, what is the most likely reason that paracrine signaling does not activate the cell that is producing the

riadik2000 [5.3K]

Answer:

The correct answer is The cells do not have proper receptor.

Explanation:

During paracrine signaling a signaling molecules are generated from one cell.The generated signaling molecule then binds to the receptor of neighboring cell to carry specific signal from donor cell to the acceptor cell.

But the signaling molecules will not bind to the cell that is producing it because that producing cell do not contain proper receptor to bind that signaling molecule.

The binding of signaling molecule to the receptor of its producing cell occur during autocrine signaling.

There are several different kinds of aquatic ecosystems. Bogs get their water from precipitation, so they don't have many Fill i

Ratling [72]

Bogs get their water from precipitation, so they don't have many nutrients.
Marsh plants are adapted to waterlogged soil
Swamps have plants like trees and shrubs.
Rivers always have flowing currents and pick up sediment as they flow.
Lakes are bodies of water on land.
Wetlands act as filters for nutrients and pollutants dissolved in the water.
Estuaries are wetland regions where freshwater rivers mix with ocean water.

Explanation:

A wetland is a biome which has both water and land that are intermixed in various ways. According to the type of the wetland, the ecosystem differs.

Bogs: Wetland with water from precipitation and no inflow or outflow of surface or ground water.

Soil: Acidic, infertile with less nutrient content

Vegetation: Acid-loving plants

Swamps: Forest wetlands near rivers and lakes.

Soil: well draining, mineral soil

Vegetation: Trees and bushes. Swamps are classified according to the vegetation, like coniferous swamp, hardwood swamp, shrub swamp etc

Marsh: Wetlands mostly inundated with water leading to waterlogged soil

Soil: Organic and mineral soil

Vegetation: Hydrophytic plants adapted to waterlogged soil

Estuaries: Wetland regions enclosed by land one side where fresh water mixes with saline ocean water.

Soil: Saline alkaline soil

Vegetation: Mangrove trees

Rivers and lakes are water bodies that form a part of wetlands.

Rivers are flowing water bodies which flows through water current and picks up sediments as it flows.

Lakes are stationary water bodies that are enclosed by land mass on all its sides.

The wetlands act as a natural filter and receive all the sediments, pollutants etc which are dissolved in water and carried by the rivers and other water sources.

A scientist wants to observe how plants respond when growing in an overcrowded area. After 200 seedlings are planted close

jarptica [38.1K]

Answer:

Correct answer is A. "making future predictions about plant behavior "

Explanation:

The most important part of the question is "overcrowded area" which leads to the future concerned scenario of modern societies. We know that, in future, the supply of resources/nutrients will be limited and thus we want to develop sustainable practices. For this, scientists often carry out the experiments where the organisms are forced to live/grow in a crowded area and then we understand how each individual responds in the presence of limited resource supply. In this experiment, I perceive that the scientist is doing a similar kind of study for a specific plant which will help him assess the future concerns of growth and development for that species as well as its interaction with the environment.
