Explanation:
Why does temperature not change during phase change?
Answer:
during phase change, the energy supplied is used only to separate the molecules,no part of it is used to increase the kinetic energy of the molecules. So its temperature will not rise, since kinetic energy of molecules remains the same.
Which characteristic of living things is missing in viruses? They can reproduce on their own. They can reproduce on their own. They can interact with other organisms. They can interact with other organisms. They can move from one place to another. They can move from one place to another. They can carry and transmit genetic material.
Answer:
The correct answer is - They can reproduce on their own.
Explanation:
Viruses are considered as living and nonliving by a different group of microbiologists and biologist as virus show characteristic of both groups living and nonliving
Living - They can move, they carry and transmit genetic material, they can interact with other living organisms and infect them, Can undergo mutation, capable to reproduce, resistant to antibiotics, and many others.
Non-living - Can be crystallized, Lack cell membrane and cell wall, inert outside the host, totally dependent on their host for their reproduction can not reproduce on their own.
1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are soluble in it. Water is such a good solvent because the molecular structure of a water molecule is polar, having a negative charge at one end and a positive charge at the other end. Which model best represents a water molecule? A. B. C. D.
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

Which of the following is NOT a form of active transport? A) cyclosis B) phagocytosis C) diffusion D) pinocytosis
Diffusion is not active and instead a form of passive transport. So the correct option is option C.
Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.
Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.
The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

What organelles found in plant cells, but not in animal cells, would you expect to find more of in the plant's leaf cells and not find very many if any
at all in the plant's root cells?
Explain why there would be more of these organelles.
Answer:
Chloroplasts
Explanation:
You would find more of these in the leaves because they have more surface area. More surface area helps them go through photosynthesis. The leaves also get more light so the chloroplasts are mostly on the leaves so the light can reach them

What happens when a ecosystem is in equilibrium
In equilibrium, an ecosystem has a balance between all organisms and their needed resources which make them to have ideal living conditions for organisms as well as climate for survival.
What is ecosystem equilibrium?Equilibrium, which is a comparatively steady state that maintains population sizes within a reasonable range, is referred to as a healthy ecosystem (not too many of a certain species alive or dead).
When an ecosystem is in equilibrium, all of the organisms and the resources they require are in balance. The environment also has the right climate for survival and excellent living conditions for creatures. The stability of the environment and the organisms is guaranteed by ecological balance. It fosters an environment that is favorable for organism growth and proliferation.

Explain why heavy fertilizer runoff and algal blooms disrupt the equilibrium (balance) in an aquatic system.
A. Fertilizer runoff:
B. Algal blooms:
Answer:
A - Fertilizer runoff can cause micro-organisms such algae to bloom out of control. B - Algae blooms suffocate the ecosystem if there is too much.
Explanation:
A - Not all fertilizer nutrients is used in agricultural production and so some of it makes its way into the excess water and therefore runs into creeks and rivers. It is also toxic to many animals in high concentrations as well as more sensitive native plants.
B - Algae blooms take a lot of oxygen out of the water, therefore suffocating natural wildlife. The decay that results from such large blooms is also problematic and takes away oxygen. Many algae likes slow moving water with little flow and in these optimal conditions with excess nutrients (Nitrogen, Phosphorus, and Potassium, NPK are the main ones) cause it to become out of control

Which process binds together sediment to form new rock?
cementation
compaction
deposition
erosion
Answer:
It will be (cementation).
That's the correct answer.
The process that binds together sediment to form new rock is cementation. The correct option is A.
What is cementation?Cementation is the process of mineral materials precipitating in the pore spaces to harden and weld clastic sediments (those generated from preexisting rock pieces). It is the final phase of sedimentary rock formation.
Through cementation, sediments become sedimentary rock. In the spaces between the sediment particles, this action causes the precipitation of minerals.
Examples of cementing include carbonate hard ground and beach rock. Black rock is a particular kind of rock that develops along the shore and is composed of a wide variety of sediment types and sizes that have been cemented together.
Therefore, the correct option is A. cementation.

Both lipids and carbohydrates are important in animal cells because both_____
A. form cell walls
B. provide insulation
C. store energy
D. contain nitrogen
Answer:
Explanation:
C the lipids makes your energy from running out soo soon
Carbohydrates and lipids are essential biomolecules for living. They both helps to store energy. Hence, option C is correct.
What is carbohydrate?Carbohydrates are macromolecules formed from the monomeric units sugars such as glucose, fructose, galactose etc. These monomer molecules polymerise to form carbohydrates such as starch, cellulose, glycogen etc.
Lipids are formed by fat and triglycerols and they they store energy in skin cells. Lipids are important biomolecules because they have significant role in the cell wall formation in plants and cell membrane formation in animals as well as aids for the transport of ions through cells.
Carbohydrates are the main source of energy in animals and plants. It is stored in the form of ATP formed by glycolysis. Hence, both lipids and carbohydrates stores energy.
