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.

What does the circulatory system do?
A. Sends hormones to the body
O B. Moves blood around the body
C. Brings oxygen into the body
O D. Defends against invaders
Moves blood around the body
The circulatory system moves blood around the body. Therefore, option (B) is correct.
What is circulatory system?The circulatory system, also known as the cardiovascular system, is responsible for the circulation and transportation of blood, oxygen, and nutrients throughout the body. It includes the heart, blood vessels, and blood. The heart pumps blood to the lungs to become oxygenated, and then circulates the oxygen-rich blood to the rest of the body through arteries.
Veins carry deoxygenated blood back to the heart, where it is pumped to the lungs to receive oxygen. The circulatory system also plays a role in removing waste products from the body, such as carbon dioxide, and helps to regulate body temperature, pH balance, and fluid balance. The circulatory system is essential to maintaining the proper functioning of all cells, tissues, and organs in the body.

4. What is evolution? Explain how artificial selection causes populations to change.
Answer:Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve. evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. Evolution can an animal to make it almost unrecognisable, like cephalopods and how they evolved to make them more buoyant

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.

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.

Water is a renewable resource used for human needs. So, the correct option is C.
What are Renewable resources?Natural resources that regenerate with time and can be used endlessly without getting exhausted are known as renewable resources. These resources are often derived from sources such as sunlight, wind, water and biomass that can regenerate or replenish themselves.
Because they provide a source of energy and materials that can be used without negatively impacting the environment or depleting resources, renewable resources are an important component of sustainable development. Water is a renewable resource used for human needs.
Renewable resources are becoming more and more important as a sustainable alternative to non-renewable resources such as fossil fuels, which are limited and can adversely affect the environment.

the distance from earth to the north star is about 430 light years. which of the following statements describes why scientists use the light year unit to measure distances in space?
a. a light year unit is very small and distances in space are very small
b. a light year unit is very small and distances in space are very large
c. a light year unit is very large and distances in space are very small
d. a light year unit is very large and distances in space are very large
Answer:
i am not sure but i think is D
A light year unit is very large and distances in space are very large. So, the correct option is D.
What is Light year?A light year is defined as the larger unit of length which is used to express astronomical distances and is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.
A light-year is expressed as the distance that light travels in a vacuum in one Julian year, which is 365.25 days because it includes the term "year", the term light-year is sometimes misunderstood as a unit of time.
1 light-year = 9460730472580800 metres
Light year is used as a unit to express distances to celestial objects, for example, if a star is 4 ly away from earth, it means that light from the star will take 4 earth years to reach us.
Therefore, a light year unit is very large and distances in space are very large. So, the correct option is D.
