Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.
Answer:
Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:
1. pH
Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.
2. Temperature:
Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

why is the late Cambrian thought of as the period of the greatest evolutionary change in life forms on earth's history?
Answer:
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears.

Explanation:
hope this helps :)
A spore grows into a mature gamete producing plant is best describe the life cycle of fern.
What is the life cycle of fern?The life cycle of the fern has two different stages such as sporophyte and gametophyte. The sporophyte stage which releases spores whereas gametophyte stage which releases gametes. Gametophyte plants are haploid whereas sporophyte plants diploid. This type of life cycle is known as alternation of generations.
So we can conclude that a spore grows into a mature gamete producing plant is best describe the life cycle of fern.

Hope it is helpful...why is intensive system the most EXPENSIVE system
Answer:
The intensive farming looks at increasing the yield in the given limited land space with a high dependency on fertilizers, labor, and machinery. ... But as extensive farming is remotely located, the labor cost, the production cost is higher. Also, the output calls for much more care and takes a while to yield the crops.

In the laboratory, scientists remove the gene for insulin from human chromosomes. They insert the gene into the DNA of bacteria. This causes the bacteria
to produce human insulin. The insulin is used to treat diabetes in humans. Which of these describe this process?
A. Recombinant DNA
B. Reproductive Cloning
C. Gene Therapy
D. DNA Fingerprinting
Answer:
A. Recombinant DNA
Recombinant DNA is created by a process called genetic recombination. In this process, we insert a exogenous gene to let another organism, a bacteria in this case, produce a protein that can not be produced otherwise

1. List five organelles eukaryotes have that prokaryotes do not have.
2. Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles,
and Golgi apparatus.
3. What is the main difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
4. Describe the three types of vesicles.
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.

Explanation:
Write a scientific explanation that explains how oxygen and carbon dioxide travel within the seed and the egg.
Carbon dioxide and oxygen travel within the seed and egg to break the energy or food inside the seed or egg. It comprises schematic steps which are responsible for these functions.
What do you mean by Seed?Seed may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.
The oxygen enters the seed and gets absorbed by the seed coat. It makes the seed coat wet and soft due to oxygen absorption. This oxygen now combines with energy that is stored inside the seed. The level of carbon dioxide increases when the process of photosynthesis will be initiated.
Therefore, carbon dioxide and oxygen travel within the seed and egg to break the energy or food inside the seed or egg.

what are the effects of sunlight on the aquatic life inhabiting amazon river
Answer:
the effects of sunlight on the aquatic life inhabiting the Amazon River. The center of all aquatic life in the Amazon is located in The Amazon Basin, the sun makes sure that all fish and plant life can sustain life.
The sunlight affects the aquatic species that lives in the Amazon River. The Amazon Basin is the epicenter of all aquatic life in the Amazon, where the sun ensures that all fish and plant life may survive.
What is Amazon Basin?The region of South America that the Amazon River and its tributaries drain is known as the Amazon basin. Approximately 6,300,000 km2, or 35.5 percent of South America, is covered by the Amazon river basin.
The Amazon basin not only contains the world's largest remaining tropical rainforest, it also harbours at least 10% of the known biodiversity, including endemic and threatened species of plants and animals, and its river contributes 15–16% of all river flow into the oceans.
The aquatic animals that inhabit the Amazon River are impacted by sunlight. All aquatic life in the Amazon is concentrated in the Amazon Basin, where the sun ensures the survival of all fish and plant life.
Thus, this is the chief effect of sunlight on the aquatic life inhabiting amazon river.

How are mid-ocean ridges formed at divergent tectonic plates?
The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.
Answer:
The stretching lithosphere is pushed up as the plates move apart.
Explanation:
Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.
I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.
