21. Explain How did Earth's environments change
from the Neogene to the Quaternary Period?

Answers

Answer 1

Answer:

Climate change and the developments it spurs carry the narrative of the Quaternary, the most recent 2.6 million years of Earth's history. Glaciers advance from the Poles and then retreat carving and molding the land with each pulse. Sea levels fall and rise with each period of freezing and thawing.

After photosynthesis, how will producers get their energy? Producers receive glucose from the intake of oxygen. Producers will release glucose into the atmosphere, feeding the ecosystem. Producers will create glucose, which is the primary source of food. Producers will receive glucose directly from any rainfall that occurs.

Answers

Answer:

After photosynthesis (Producers will create glucose, which is the primary source of food)

Explanation:

The biotic component of an ecosystem is made up of all living organisms in it. These organisms are divided into two main groups according to the way they feed:

--> Producers (autotrophs) and

--> Heterotrophs.

Producers are organisms that are able to use sunlight or chemical energy to manufacture their own food (glucose) from simple inorganic substances. This process is known as photosynthesis. Producers include all green plants, photosynthetic protists and some bacteria

Producers extract inorganic nutrients and chemical energy from their non-living environment, that is, from the abiotic component of the ecosystem. Since autotrophs are the only organisms that can produce food in an ecosystem, they are also known as PRIMARY FOOD PRODUCERS.

PRODUCERS use some of the food they produce for their activities and building their body tissues (growth). The rest is stored in various parts of the body.

Answer: Its C,  Producers will create glucose, which is the primary source of food.

A. “glucose” and “carbon dioxide” should be switched
B. No errors
C. “water” and “oxygen” should be switched
D. “chloroplasts” should be “mitochondria”

Answers

I think its B the answer for your questions not sure
Hope u find it

Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen. Option A is the right answer.

What is photosynthesis?

Photosynthesis is the process by which green plants prepare their own nutrients with the help of sunlight, water, and carbon dioxide.

Photosynthesis helps plants to prepare their own food, these plans are called autographs.Photosynthesis takes place inside the protoplast.This process takes place in some other organisms other than green plants.Chlorophyll is the green pigment that is required for this process to take place.The end products that are formed in the process of photosynthesis are glucose and water.

Hence Option A is the right answer.

Which is a benefit of binomial nomenclature?

2.Increased understanding and communication
3.Reduced plant-related poisoning
4.Better understanding of genetics of plants

Answers

2) Increased understanding and communication.

Various cultures and societies shape individual names for a particular organism. However, binomial nomenclature breaks this barrier to allow the scientific community to communicate more efficiently.

For example, the panther or mountain lion can simply become Puma concolor — thus, eliminating confusion. I hope this helps.

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes closest to explaining the basis for placing these organisms in different taxa, well before relevant data from molecular systematics became available?

Answers

Answer:

Due to other differences.

Explanation:

The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.

define and describe osmosis​

Answers

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

1)Fishing boats have decreased the number of herring in the sea. Explain why that could affect the number of offspring puffins can raise.
2) Which animals have a bigger food supply now there are fewer herrings?
3) Global warming is expected to reduce the biomass of phytoplankton in the oceans. What effect will that have on the rest of the food web?​

Answers

Explanation:

1) When the number of herrings decrease, the food available for the puffins decrease and therefore they will not be able to feed their offspring. This will cause the number of offspring to decrease.

2) Any other animal(s) which hunts and eats the same prey as a herring will now have a bigger food supply.

3) When the biomass of phytoplankton decrease, the next animal in the food web will not have any food and their numbers will decrease, decreasing the number of the animals next in the web, as they too lose their food. This will continue for the rest of the food web and the number of animals will decrease.

For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?

Answers

Answer:

beak depth is a complex (quantitative) trait

Explanation:

Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community

Answers

Answer:

The elephants are the keystone species in this ecosystem.

Explanation:

The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.

This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.
