PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.

Answers

Answer:

Autotroph

Explanation:

An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.

According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

In which way does the composition of soil, an abiotic factor, rely on living things?

Bacteria erode rocks into smaller particles that are added to the soil.

Bacteria break down dead matter and wastes, releasing nutrients into the soil.

Insects take in air and minerals and release these materials into the soil as wastes.

Insects make small tunnels in the soil. Bacteria use these tunnels to break down dead matter.

Answers

Answer:

Soil Layers. Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.

which of the following are reasons that crops like soybean and palm are called cash crops?
◾️their leaves are shaped like dollar bills.
◾️they grow quickly.
◾️they make a quick profit for farmers
◾️they are used in a variety of products

Answers

Answer:

"They are used in a variety of products" or "They make a quick profit for farmers."

You would say its "They grow quickly" but I took the examine and it was incorrect.

Explanation:

This was pulled straight out of the lesson

Agriculture, or farming, is the largest driver of deforestation in which vast areas of natural forest are burned or cleared to raise cattle or grow crops. Usually forests are burned to quickly make the land available for planting. Sometimes fast growing crops, like palms and soybeans, are planted on lands cleared of their forests; these crops make a quick profit for the farmers. Palm oil and soy are used in a wide array of products ranging from toothpaste, chocolate, animal feed, and cosmetics.

Why do you think these crops are sometimes called "cash crops"?

Cash crops like palm and soy grow quickly and make money fast.

The following are reasons that crops like soybean and palm are called cash crops:

They make a quick profit for farmersThey are used in a variety of products.

So, the correct options are C and D.

What are Cash crops?

Unlike subsistence crops, which are grown to supply the basic needs of the farmer and his family, cash crops are agricultural products grown with the intention of being sold for profit. Cash crops are often traded on international markets and are generally produced on a large scale, often employing industrial agricultural techniques.

Cereals, fruits, vegetables, and industrial crops such as cotton, tobacco, and rubber can all be considered cash crops. Soybeans, coffee, cocoa, tea, palm oil and sugarcane are some of the most popular cash crops. The economy, environment and social welfare of a place can be affected by cash crops in both positive and negative ways.

So, the correct options are C and D.

Wolves are predators of deer. What is most likely to happen to the deer population if the wolf population increased?

Answers

Hello !⛧bayerife15⛧ I'm glad you asked!

My name is ⚝Tobie⚝ and I will walk you through every step of the way and I will make sure you understand this a bit better!

So what would happen to the deer population if the wolf population increased?

i stay the same

ii increase

iii decrease

iiii become extinct

__________________________________________________________

The population of deer would decrease .

The population of deer would decrease because  the population of wolves

goes up. Since the population goes up they need food and the food they eat

are deer .It would be a bit different if the wolf population decreased .If the

wolf population decreased the deer population would increase which could

lead to overpopulation.

Why are deer important?

Deer are important for our environment because they help other animals

survive and with out them many animals such as wolves and many other

predators would have a hard time catching food.There would be a huge

imbalance in the food chain as well. But when deer overpopulate it becomes

a problem.There will be less food for birds and many other animals.

There would also be a spread in diseases that deer bring .

Hope this helps!

It is most likely that the deer population will decrease as the wolf population increases. Therefore, the correct option is C.

What is Population?

A population is a collection of members of the same species that coexist in the same location and interact with each other. Size, density, age structure, and genetic makeup all contribute to the definition of a population. It is most likely that the deer population will decrease as the wolf population increases.

This is due to the fact that wolves are predators of deer and their hunting will be more frequent as their population decreases. Wolves would have fewer prey to eat as deer populations would decline, which could prevent the expansion of their own populations. A predator-prey cycle describes this interaction between populations of predators and prey, which can lead to changes in population size over time.

Therefore, the correct option is C.

What evidence is there that the 15 species of finch all evolved from one common ancestor?

Answers

Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources. This illustration shows the beak shapes for four species of ground finch: 1. Geospiza magnirostris (the large ground finch), 2. G. fortis (the medium ground finch), 3. G. parvula (the small tree finch), and 4. Certhidea olivacea (the green-warbler finch) the Grants measured beak sizes in the much-reduced population, they found that the average bill size was larger. This was clear evidence for natural selection of bill size caused by the availability of seeds. The Grants had studied the inheritance of bill sizes and knew that the surviving large-billed birds would tend to produce offspring with larger bills, so the selection would lead to evolution of bill size. Subsequent studies by the Grants have demonstrated selection on and evolution of bill size in this species in response to other changing conditions on the island. The evolution has occurred both to larger bills, as in this case, and to smaller bills when large seeds became rare.

All of them evolved from one rooted species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty eco-space, is known as adaptive radiation.

What is evidence of common ancestry and how do they explain evolution?

Homologous structures provide proof for a common origin, while analogous structures show that similar selective pressures can produce similar adaptations. Alikenesses and differences among biological molecules can be used to determine species' relatedness.

Thus, adaptive radiation is one of the reasons.

C) The types of plants and animals that live in the forest are reasonably stable.

The statement that describes a forest ecosystem that has not experienced any natural disasters in the past 100 years is, "The types of plants and animals that live in the forest are reasonably stable," hence option C is correct.

What is a forest ecosystem?

Along with nonliving (abiotic) elements like soil, water, air, and landforms, forests also contain living (biotic) elements like trees, animals, plants, and other life things. A forest ecosystem is made up of all of these elements.

The numerous plant and animal species residing in a forest ecosystem are generally stable if it has not recently been subjected to any disturbances or natural disasters.

Therefore, plants and animals that live in the forest are reasonably stable, so this ecosystem not experienced any natural disasters.
