What are the effects of soil pollution?
Answer:
Soil pollution produces negative effects for the environment.
Explanation:
Soil pollution can cause many different negative effects for the environment and for organism health. Some effects are:
Nutrient imbalance - plants cannot get enough nutrients in one area since the soil is either devoid of nutrients or high one 1 nutrient and too low on othersAcidification - pollution can cause the soil to become acidified, affecting organisms and the water cycle. This acid will be harmful to plants and harmful to animals drinking it. Since it also affects the water cycle, it can affect humans by burning skin if touched or polluting our drinking sourcesContamination of groundwater - with soil pollution, it can seep deep into the Earth. This can cause natural aquafers and underground lakes/water to become polluted as well, giving us even less freshwaterAll in all, soil pollution is not positive at all and should be reduced at all costs to help nature and our planet Earth.

This wood mouse is eating a blackberry. The wood mouse's small intestine will absorb particles of important nutrients, including sugar, water, and vitamins. But some waste from the blackberry will be left over.
What happens to waste from food? Select all that apply.
A.the waste is released from the body B.the waste is moved through the large intestine C.the waste is released into the blood or D.water from the waste is absorbed in large intestine (multiple choice)
Answer:
B
D
A
Explanation:
The essential nutrients and minerals are absorbed from the waste as they pass through the small intestine. From the small intestine, the waste is allowed to pass through the large intestine where it absorbs excess water.
After the absorption of excess of waste, the remaining solid waste is known as feces and then it is thrown out of the body.
Option, B,D and A are correct

Are the current life forms similar to those of 3.8 billion years ago? How do we know?
Answer:
No, not really. Over time, organisms have grown much more complex. Photosynthesis happened around 3.4 billion years ago and respiration around 2 billion years ago. These all serve as a testimony to the fact that organisms are in fact growing more complex. We have seen photoautotrophs arise, from the simpler chemoautotrophs, and they now in fact dominate the array of producers! Organisms don't only do fermentation now; they can also do anaerobic respiration and aerobic respiration too! Thus, current life forms are a lot more different today than 3.8 billion years ago.

White blood cells protect against _____ and aid in blood clotting when injuries are sustained
Answer:
pathogens
Explanation:
White blood cells also known as leukocyte does not have hemoglobin. However, it is capable of defending the body against any kind of infection and disease caused by foreign biotic and abiotic elements or pathogens by producing antibodies against them.
Kono Dio Da!!!!
White blood cells protect against pathogens and aid in blood clotting when injuries are sustained. a particular sort of blood cell that is produced in the bone marrow and present in both the blood and lymphatic tissue.
What is the role of White blood cells?The immune system of the body includes white blood cells. They support the body's defenses against illness and infection.
Innate immunological processes carried out by leukocytes, specifically monocytes, macrophages, and neutrophils, interact with the hemostatic system to express and release coagulation and fibrinolytic factors.
The job of protecting wounds is performed by a different class of blood cells known as a macrophage, a sort of white blood cell.
Therefore, this cell controls the healing process and fights infection.

Which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid
when doing fieldwork?
to wash rock samples to make them easier to study
to wear away large areas of rock to see what is underneath
to test for the presence of carbonate minerals in a rock
to use as an emergency eyewash in case rock dust gets in the eyes
Answer:
C, to test for the presence of carbonate minerals in a rock
Explanation:
I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes
Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
Test for carbonate mineralsHydrochloric acid is used to test for presence of carbon iv oxide in compounds.
When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.
Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.
Thus, the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.

The researcher had hypothesized that the addition of the vitamin that is similar in structure to NADH would increase the activity of the mutated NADH dehydrogenase enzyme in individuals with the disorder. Explain how the vitamin most likely increased the activity of the enzyme
Answer:
It is expected that the mutation helps the enzyme to bind to the vitamin, and this interaction may be necessary to maintain the activated state of the enzyme.
Explanation:
The NADH dehydrogenase converts nicotinamide adenine dinucleotide (NAD) from its reduced form (NADH) to the oxidized NAD+, thereby this enzyme is required for generating ATP by electron transport.

Explain why an increase in CO, in Earth's atmosphere, might cause the temperature of the atmosphere to increase and lead to climate change.
Answer:
When the carbon dioxide concentrations rise, the air temperature will rise as well due to the greenhouse gases heating up and multiplying.
Explanation:
Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapour accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapour evaporates into the atmosphere—which then amplifies greenhouse heating.
Which of these statements is true about autotrophs, but not heterotrophs?

B. They use chlorophyll and oxygen to make carbon dioxide and water.
C. They use sunlight, water, and carbon dioxide to make sugars.
D. They use sunlight, water, and oxygen to make chlorophyll.
plz help
Answer:
c
Explanation:
The statements is true about autotrophs, but not heterotrophs is that they use sunlight, water, and carbon dioxide to make sugars. Thus, option C is correct.
What plants use to make food?The plants use sunlight, water, and carbon dioxide to make sugars as well as food. Organisms can be divided into autotrophs and heterotrophs according to their pathway of producing food and energy. Heterotrophs are that organism which depend on another organism for their food and energy. They get their energy from carbohydrate, protein, and fat.
Those organisms that are able to make and produce energy from energy-containing organic molecules such as glucose from inorganic raw material such as water and by using light energy such as sunlight are autotrophs. Plants are the prime autotrophs, they produce their food and energy which is sugar from water, sunlight and carbon dioxide using photosynthesis.
Therefore, The statements is true about autotrophs, but not heterotrophs is that they use sunlight, water, and carbon dioxide to make sugars. Thus, option C is correct.
