Photosynthesis is the primary funtion of the leaves.
Explanation:
Photosynthesis is defined as the chemical process of converting light energy into chemical energy in a form of food or sugar. Leaves contain most of the chloroplasts in plants that are responsible in capturing light for photosynthesis to occur.
Leaves are naturally green to serve their purpose. This green color is caused by the reflection of the green portion of the visible light spectrum by the green coloring pigment, chlorophyll. Chlorophyll, that is contained in chloroplasts, captures certain wavelengths of light, as energy to initiate photosynthesis. As a result, we get food from plants.

Answers

Answer:

Explanation:

There are two types of succession. The first is primary succession. Primary succession occurs in an area that has not been previously occupied by a community. Places where primary succession occurs
include newly exposed rock areas, sand dunes, and
lava flows. Simple species that can tolerate the often-
harsh environment become established first. These organisms help enrich the soil, allowing other species to become established. The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.

Which best describes what Shah is doing? replication repetition both repetition and replication neither repetition nor replication

Answers

Answer:

This question is incomplete. The complete part of the question is as follows:

Shah did not trust the results of an experiment that she had read about, so she is conducting the experiment herself. She goes through the same set of steps and measures the effect of the amount of sugar on a single organism.

Which best describes what Shah is doing?

The answer is A. Replication

Explanation:

In an experiment, replication is the process of repeating an experiment that was formerly conducted by another experimenter in order to ensure accuracy. Note that, an experiment is 'replicated' under the same conditions as it was conducted previously.

This is the case in this question involving Shah who conducted an experiment herself because she didn't trust the results of the experiment she read about. She conducted an experiment that has already been conducted by another experiment, hence, it is a REPLICATION.

In 1-2 sentences, explain why mutations can be beneficial to an organism.

Answers

Answer:

Some mutations can change genetic variation in a way where an organism can adapt to the surrounding environment. Mutations created gills, which allow fish to breath underwater. Mutations allowed giraffes to reach leaves higher up on trees so they can get food. Mutations also allowed humans to be able to adapt to any environment and situation and continue growing.

Explanation: Brainliest is always appreciated

Mutations are random changes in the DNA sequence of an organism's genome. Mutations can be beneficial to an organism because they can lead to genetic variation, which can allow for natural selection to occur.

What is mutation?

Mutation is a process that refers to a change in the genetic material (DNA) of an organism. The genetic material carries the information that determines an organism's characteristics and traits, like eye color, hair color, or susceptibility to certain diseases. Mutations can happen naturally, or they can be induced by various factors such as exposure to radiation, chemicals, or viruses.

Mutations can affect a single base pair of DNA, a larger segment of DNA, or an entire chromosome. They can be classified in many ways, but one of the most common ways is by their effect on the genetic material.

Describe and the explain the changes in blood lactic acid and concentration shown in the graph || guys someone please help i’m failing bio so hard!!

Answers

During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.

1. Explain how the energy flows within living systems. Include the
following concepts:
• 10% Energy Transfer
• Food Web
• Food chain
(3 points)
2. Explain how energy is transformed through the process of
photosynthesis. (2 points)

Answers

Answer:

Explanation:

energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. Energy may be lost in living systems as it flows through them.

Photosynthesis is  the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

10% energy transfer is the law of energy transfer in which about 10% of the energy is transferred to the next trophic level in an ecosystem.

What is the energy flow in an ecosystem?

Energy flow is the flow of energy which occurs through the living things within an ecosystem. All the living organisms in an ecosystem can be organized into different groups such as producers and consumers, and the producers and consumers can be further organized into a proper food chain. Each level within a food chain is called as trophic level.

1. 10% energy transfer is the law which states that 10% of the total energy is transferred to the next trophic level and 90% is lost into the atmosphere.

Food web is a network of interlinked food chains. In this different organisms are produce at each trophic level which provides the organism with different options for their food.

Food chain is a linear network of different organisms at different trophic levels in an ecosystem.

2. Photosynthesis is the process of energy transformation in which light energy in the form of sunlight is transformed into chemical energy in the form of chemical bonds present in the carbohydrate molecules.

HELP! What are some of the reasons Humans depend on the ocean? - How do humans impact the ocean? - Since we humans depend on the ocean a lot, what should we do to take better care of our ocean?

Answers

For an ecosystem that covers 70 percent of the planet, oceans get no respect.

All they’ve done is feed us, provide most of the oxygen we breathe, and protect us from ourselves: Were it not for the oceans, climate change would have already made Earth uninhabitable.

How?

The oceans have gamely absorbed more than 90 percent of the warming created by humans since the 1970s, a 2016 report found. Had that heat gone into the atmosphere, global average temperatures would have jumped by almost 56 degrees Celsius (100 degrees Fahrenheit).

But as vast as the seas are, there is a limit to how much they can absorb, and they are beginning to show it. Today, on World Oceans Day, Human Nature examines some of the ways that climate change affects life in the oceans — and what that means for humanity.
