Answer:
Veins arteries and capillaries
The structures in the human body that carry out some of the same function as xylem and phloem are veins, arteries, and capillaries.
What do you mean by Xylem and Phloem?Xylem and phloem are the vascular tissues that transport water, minerals, and food from the roots to the leaves and from the leaves to the roots respectively.
Xylem and phloem represent homology with the veins and arteries. Veins carry blood back towards your heart, while arteries carry blood away from your heart.
Capillaries are blood vessels that carry the oxygen and nutrients from the blood and transport them into the tissues and organs. It also requires the elimination of the waste products away from your tissues.

Which of the following does water pollution affect: surface water, ground Water, or ocean water? A)Pollution affects surface water and ground water only.
B)Pollution affects surface water, ground water, and ocean water.
C)Pollution affects surface water and ocean water only.
D)Pollution affects groundwater and ocean water only.
Water pollution includes any kind of water masses or currents. Option B is correct. Pollution affects surface water, ground water, and ocean water.
What is water pollution?
Water pollution can be defined as the abnormal accumulation of strange elements in the water with harmful consequences to natural ecosystems.
Water pollution involves all the possible ways in which any water body can be contaminated with harmful elements.
The most damaging source of water pollution is human activities, producing the biggest damage to natural ecosystems.
Contaminating elements might be either gasses, solid material, or liquid material. Chemical elements, microbiota, heavy metals, and sediments affect all forms of life.
As said before, several sources can contaminate water masses, and they do it directly and indirectly.
Directly pollution occurs when a strange element is thrown directly into the water. They can be thrown directly into a river, a lake, the sea, or the ocean.
Indirect pollution occurs when pollutants travel from other places and contaminate other masses of water. For instance, a polluted river contaminates the lake where it ends. The lake pollutes the river that begins in the lake. This last river ends in the sea and takes all pollutants to the sea.
We can affirm then that water pollution affect surface water, ground water, or ocean water. Option B is correct. Pollution affects surface water, ground water, and ocean water.

Deforestation is the second leading cause of global warming (climate change) worldwide, and it produces about 24% of global greenhouse gas emissions. Deforestation in the tropical rainforests contributes more carbon dioxide to the atmosphere than the sum of all cars and trucks that drive on the world’s roads.
Why would deforestation this lead to more carbon dioxide?
a
The changed habitats support more animals, like native birds and mammals, that produce more carbon dioxide.
b
The increased amount of timber harvested produces oxygen gas, which encourages the wildlife to generate carbon dioxide.
c
Loss of trees leads to a decrease of the ability of forests to act as carbon sinks to remove carbon dioxide from the atmosphere.
d
Equipment used for clear-cutting produce metric tons of carbon dioxide, which is released into the atmosphere during the process of deforestation
Answer:
C
Explanation:
According to Worldwildlife.org, Forest play a critical role in mitigating climate change because they act as a carbon sink - soaking up carbon dioxide that otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns.

How does adding carbon dioxide to the ocean
affect its pH?
Provide an explanation for the results (or what should have happened) using SCIENTIFIC REASONING
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Could melanin granules be moved by dynein and kinesin along an actin microfilament?.
We can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.
Why can these substances not be moved along a microfilament?This has to do with the fact that these proteins are specific to microtubules, and therefore are not able to move along microfilaments. This is why the dynein and kinesin motor proteins would not be able to transport the granules along microfilaments.
Therefore, we can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.

Answer:
It is false not true that is the answer
True or False: In a box and whisker plot, 50% of the data is between Q1 and the median
Answer:
Minimum = 0%
Q1 (Lower Quartile) = 25%
Median = 50%
Q3 (Upper Quartile) = 75%
Maximum = 100%
That is true. In a box and whisker plot, Q1 is the first quartile (first 25% of the data) is between the lower quartile (Q1) and the median. The median is the middle, so 50% will fall between Q1 and the median. It's important to understand the various measures of central tendency and how they can be used to analyze the spread of data within a given set, which can provide valuable insights and understanding about the overall trends present within the data.

Answer
D.) C and D
Explanation:
It may look like B and C, but the sun hardly reaches up in the north, plus its axis is shifted so it's not technically summer for them yet, this leaves the bottom, which will rotate and give both sides the taste of summer glory.
Once the earth rotates more, it will be summer for B. and A.

Which of the following is least involved in the mechanical breakdown of food, digestion, or absorption?.
Answer:
Esophagus
Explanation:
In the digestion and absorption of food, the esophagus is the least involved.
It is a part of the digestive system, but all it does is simply pass the food down to the stomach.
The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.
Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.
A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.
Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.
The majority of digestion and nutrient absorption occurs in the small intestine.
Thus, the correct option is d.

please what is meant by photosynthesis
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water, In most cases, oxygen is also released as a waste product that stores three times more chemical energy than the carbohydrates. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
