Besides a radio signal, what would you use to rescue people buried in an avalanche?
Answer:
avalanche transceivers are devices that actively transmit and search for an electronic signal at a limited range. They are specifically designed to locate victims buried by avalanches and are generally regarded as the fastest way to find someone in a full burial. Because of this, they are typically listed first in the three avalanche rescue items skiers need when venturing into the backcountry: transceiver, shovel, probe.

During anaphase, part of the _____________ can be seen attached to the centromere of each sister chromatid as they separate.
mitotic spindle is the answer
During anaphase mitotic spindle is attached at the centromere of each sister chromatid because it attaches the chromosome to the opposite spindle pole.
What is the mitotic spindle?Protein complexes connect microtubules to the chromosomal midpoint (the centromere) (kinetochores). The connected microtubules depolymerize and shorten, causing movement that pushes chromosomes toward centrosomes situated at either pole of the cell.
The mitotic spindle is a structure that separates the chromosomes. The mitotic spindle is composed of multiple long proteins known as microtubules that are connected to a chromosome at one end and to the cell pole at the other.
The anaphase stage in the cell cycle prepares to spare sister chromatids reday for moves it toward the opposite spindle pole.
Therefore mitotic spindle is seen centromere of each sister chromatid as they separate and move toward the spindle pole.

What is a medulla? What do forensic scientists use this for?
Answer:
the inward district of an organ or tissue, particularly when it is unmistakable from the external area or cortex (as in a kidney, an adrenal organ, or hair).
"the adrenal medulla produces adrenaline"
What do legal researchers involve this for? Scientific researchers might search for the presence or nonappearance of a medulla, which is a bunch of cells that goes through a hair. The medulla is ordinarily unique relying upon the species that the hair came from, which makes it one method for recognizing creature and human hair.

Liptin is the hormone made by adipose tissue that promotes satiety and a sense of fullness which reducing appetite.
What is liptin?Leptin is a hormone which is made up of adipose cells that helps to regulate energy balance by inhibiting hunger which in turn reduces fat storage in adipocytes.
So we can conclude that Liptin is the hormone made by adipose tissue that promotes satiety and a sense of fullness which reducing appetite.

In a river ecosystem, dissolved oxygen concentrations drop quickly downstream from a point-source input of organic matter into the river. This effect is due to
Answer:
increasing bacterial activity as organic matter decays
Explanation:
that would be your answer
Dissolved oxygen concentrations drop quickly downstream from a point-source input of organic matter into the river due to the breakdown of organic compounds by bacteria.
What is dissolved oxygen?The amount of oxygen dissolved in water is known as dissolved oxygen (DO). The atmosphere and aquatic vegetation provide oxygen to water bodies. Running water, such as a fast-moving stream, dissolves more oxygen than still water, such as that found in a pond or lake.Why does DO concentrations drop quickly downstream?The river's upstream environment is often cold and harsh, preventing organic life from flourishing. However, as you proceed downstream, the riverine environment normally becomes a little calmer, allowing for more oxygen-consuming river life like bacteria, which degrade and absorb oxygen as they are swept downstream producing organic products.A high organic content in water decreases the amount of dissolved oxygen in water.
hence the DO is reduced in downstream due to breaking down of bacterial products.

Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. she found that the percentages of both gases were different in each. what other gas would most likely also have different amounts in inhaled and exhaled air? ozone (o3) hydrogen (h2) water vapor (h2o) sulfur dioxide (so2)
Breathing is the process of inhaling oxygen and removing carbon dioxide. Just like oxygen and carbon dioxide, Water vapor also have different amounts in inhaled and exhaled air.
What is respiration?The process of inhaling oxygen and releasing carbon dioxide and releasing energy is called respiration.
The first step towards respiration is breathing, which is done by inhaling oxygen and exhaling carbon dioxide through nostrils.
The amount of different gases varies in environment.
During breathing amount of inhaled air contains different percentage of oxygen and carbon dioxide as compared to exhalation.
The reason for such variation includes the use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct by the cell.
Water vapor is also inhaled and exhaled in different amounts just like oxygen and carbon dioxide.
Thus, the correct option is C.

When a person becomes infected with the influenza virus, cell-mediated immunity is activated. Why would the influenza virus initiate cell-mediated immunity? Describe the process of cell-mediated immunity as it would attack the influenza virus.
Cell-mediated immune reaction involve the destruction of infected cells by cytotoxic T cells, or the ruin of intracellular pathogens by macrophages The activation of naive T cells in reaction to antigen, and their subsequent expansions and differentiation, constitutes a primary immune response.
How does the influenza virus attack the cells?The viruses connect to cells within the nasal routes and throat. The influenza virus's hemagglutinin (HA) surface proteins then lash to the sialic acid receptors on the surface of a human respiratory tract cell.
