how are layers that form ice similar to tree rings
Answer:
each new layer or ring represents a year of growth, depending on its thickness, you can tell if it had good growth or not so good growth.
They can both tell you things about the past climate changes.The tree rings represents each year and the ice sheets represents the past climate conditions.
A physician wants to observe the monocytes from a patient. Design an experiment the physician can perform to retrieve monocyte cells.
Answer:
White blood cells can be called the strong defender of our body from foreign substances. These cells are responsible for increasing the immunity power of a person.
Explanation:
Monocytes cells are also called white blood cells. These cells play a role an antigen that fight with outer danger and protect other white blood cells as well and prepare other cells to reduce the dead blood cells and renovate new blood cells.
These cells prevent cancer cells and fight against foreign antigens or particles. The Monocytes are the cells that develop in the bone marrow of a person and develop red blood cells.
In white blood cells, some macrophages cells are called the scavengers in the bone marrow that eat foreign particles and increase the immunity power of the person. The diagnose can be done with the help of blood testing.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.

Which of the following best compares viral reproduction to reproduction in other organisms?
A. Viruses do not contain genes that are replicated and passed on.
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce.
C. Viruses and single-celled organisms use mitosis as a reproductive process.
D. Viruses can only reproduce asexually while other organisms have a choice.
Answer:
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce
Explanation:
Virus is an organism that is incapable of replicating on its own without infecting a living host cell. A viral cell is dependent on a living host to replicate and express its genes. Hence, the infection cycle of a virus is its reproductive life cycle.
Other living organisms e.g plant, bacteria, fungi etc. have the ability to reproduce i.e. multiply on their own through asexual or sexual means. However, on the contrary, a virus must infect a living host, hijack the replicational abilities of the host cell in order to reproduce. Based on this, a virus employs a lysogenic or lytic cycle or both on its host to reproduce.

The hypothalamus controls excretions from the pituitary gland. It causes the release of some hormones from the pituitary by direct nervous control, and others by secreting releasing and inhibiting factors that stimulate the pituitary to secrete hormones. Which best describes the hypothalamus? It is a connection point between the nervous and endocrine systems. It is both an exocrine and endocrine gland. It is referred to as the “master gland.” It secretes its contents into ducts.
Answer:
The hypothalamus controls our nervous system and hormones that control how we feel
Explanation:
The statement "It is a connection point between the nervous and endocrine systems" best describes the hypothalamus.
What is a hypothalamus?The hypothalamus is a region of the brain that is responsible for maintaining homeostasis in the body by regulating various physiological processes.
It is a crucial link between the nervous and endocrine systems, as it controls the release of hormones from the pituitary gland by both direct nervous control and secretion of releasing and inhibiting factors.

A. The separation of functions ensures that photosynthesis can continue running no matter what light conditions are present.
B. The presence of separate light-dependent and light-independent reactions ensures that the plant can survive through day and night.
C. Thylakoid and stromal fractions correspond to regions in the intact chloroplast that have overlapping functions.
D. Compartmentalization within the chloroplast keeps the light-dependent and light-independent reactions in close proximity but separated.
Answer:
A. The separation of functions ensures that photosynthesis can continue running no matter what light conditions are present.
Explanation:
What happens to electrons when pigments in Photosystem II absorb light? They become excited and break down the pigments to release ATP. They are pumped across the membrane into the thylakoid. They move through an electron transport chain to Photosystem I. They combine with oxygen and hydrogen to produce water.
Answer:
They move through an electron transport chain to Photosystem I.
Explanation:
High-energy electrons move through the electron transport chain from photosystem II to photosystem I. Energy from the electrons is used by the molecules in the electron transport chain to transport H+ ions from the stroma into the inner thylakoid.
Answer: They move through an elctron...
When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. The high-energy electron is passed to an acceptor molecule and replaced with an electron from water.
