Identify organelles in a plant cell with the diagram below.

Transport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules. When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.

Answer:

Eukaryotic cells are cells with a nucleus (such as animal and plant cells) whereas Prokaryotic cells are cells without a nucleus (such as a bacterium cell)

Explanation:

Answer:

x- summer y- winter

Explanation:

It looks like x is closer to the equator and would therefore have hotter weather, meanwhile y looks like it's closer to the top of the planet (where its a lot colder)

Answer:

C.

Explanation:

Primary succession is where it is a new area, not one where the area was simply made uninhabitable which gets rid of A, and B. C goes into more detail as to what actually happens as lichens consume the rocks while weeds come in afterwards due to the soil being formed since the lichen has broken down the rocks. Shrubs follow because enough soil has formed. followed by hardwoods and trees cause the roots of previous plants have formed enough soil for larger organisms and eventually a forest

Answer:

The nervous system includes both the Central nervous system and Peripheral nervous system. The central nervous system is made up of the brain and spinal cord, and the peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.

Answer:

Primitive Earth (Before life) contained no or very little Oxygen (element#8)

According to scientific theory:

Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.

Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.

Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.

Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.

The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.

Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.

Explanation:

jk but he is right

Answer: Water

Explanation:

A community is the occupied space by a population of two or more species. Water is a community component of a wetland ecosystem. Thus, option A is correct.

Wetland is a type of ecosystem that comprises water reservoirs and has an excess of stored water in the form of bogs, marshes, and swamps. A wetland ecosystem includes many biotic and abiotic factors that interact and live together.

The wetland ecosystem is characterized by the presence of water throughout all the years. It is a valuable ecosystem that absorbs excess precipitation so as to avoid flooding and soil erosions. Hydrology, soils, and biology are the main components of the ecosystem.

Therefore, option A. water is the component of the wetland ecosystem.

Answer:

B snsjididiwhejtofijsndixichhdje

Your answer is → compartment within the cell called a nucleus

In a cell, DNA would most likely be found inside the nucleus which is known as the controlling center of the cell.

DNA stands for Deoxyribonucleic acid. It is considered the most common genetic material of living organisms. The genetic information of a particular organism is encoded with these segments, known as DNA.

The process of transcription is initiated within the nucleus of the cell which transforms DNA into mRNA. It is known as the brain of the cell. Due to compartmentalization in eukaryotic organisms, a well-defined nucleus has appeared which helps in the transfer of genetic information from one generation to the next.

Therefore, the nucleus is the region where DNA is most likely found within the cell.

2. You see how different structures look under an immense magnification that you cannot see with the naked eye.

3. You see how animal and plant tissue is different.

Answer:

The answer would be B,

Explanation:

Increased size of gray areas is the change over time in the landsat maps that would most likely be associated with the contaminated water habitats nearby. Thus, the correct option is B.

Landsat is a moderate spatial-resolution imagery which provides the large areas of repeated data coverage at a scale that enables the users to see the detailed human-scale processes, such as urbanization, but not the individual houses.

The Landsat series of Earth Observation satellites have continuously acquired images of the Earth's land surface, which provides uninterrupted data to help the land managers and policymakers to make informed decisions about the natural resources and the environment. The increase in the gray areas in the landsat maps is associated with the water contamination.

Therefore, the correct option is B.

Answer:

ok so

Explanation:

If the cell membrane of an animal cell is damaged, it would lose the ability to take in nutrients and excrete wastes. This would hinder the cell's capacity to create necessary materials and maintain proper functioning. Thus, the correct option is (b).

The correct response is option (b). The transport of chemicals into and out of the cell is regulated by the cell membrane, which acts as a selectively permeable barrier. Essential cell processes like food intake and waste elimination would be impeded if the membrane were to get disrupted.

This would impede the cell's capacity to produce required components through nutrient-dependent processes like metabolism. There would be a significant negative impact on the cell's general health and function, which could result in cellular malfunction, slowed growth, and ultimately cellular death.

Answer:

Velocity

Explanation:

Given the change in positive (direction) over time we are given the velocity formula.

V = Change in direction/Change in time

Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
