When you do something anaerobic, your body makes a natural chemical called __________ that is like emergency energy for your muscles.
Group of answer choices
lactic acid
oxygen
testosterone
sweat
Answer:
Sweat?
Explanation:
Answers:
lactic acid

What are the three types of forests age and structure?
Answer:
Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia, The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,
Explanation:
Hummingbirds need large amounts of energy to flap their wings between 60 and 200 times per second. Their wings beat so rapidly that it is difficult to see them move. They often appear suspended in air for extended periods of time without changing their location. Hummingbirds have long bills and grooved tongues to reach into flowers to feed on flower nectar. They also feed on insects.
The body system most directly interacting with the skeletal system to enable hummingbirds to beat their wings between 60 and 200 times per second is the-
F.
muscular system.
G.
integumentary system.
H.
endocrine system.
J.
circulatory system.
How does the circulatory system work as a defense system?
Answer: It provides protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. Clotting mechanisms are also present that protect the body from blood loss after injuries.
Answer:
The human circulatory system has a complex network of blood vessels that reach all parts of the body. This extensive network supplies the cells, tissues, and organs with oxygen and nutrients, and removes carbon dioxide and waste compounds.

3. What is the general pattern of current flow and temperature within the Atlantic basin?
Answer:
Have both clockwise and anticlockwise directions and warmer temperature.
Explanation:
Atlantic oceans have a circular pattern of surface currents that moves in the clockwise direction in the Northern Hemisphere and counterclockwise direction in the Southern Hemisphere while on the other hand, the temperature of the Atlantic basin is warm and having high salinity in the water. The Atlantic Ocean has about 9 degrees Celsius more warmer than the water of Pacific Ocean that leads to the warmer climate of Atlantic basins.

Cytoplasm - supports and protects all cellular organelles.
Endoplasmic Reticulum - aids in making proteins, carries materials through the cell.
Ribosome - synthesizes proteins.
Mitochondria - breaks down sugar molecules to release energy, site of aerobic cellular respiration.
Golgi Complex - modifies proteins made by the cell, package and export proteins.
Vacuole - store food, water, metabolic, and toxic waste.
Lysosome - break down old cell parts, break down larger food molecules into smaller pieces.

what is made when a sperm cell combines with the polar nuclei?
Answer:
Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).
Answer:
endosperm
Explanation:
The second fertilization results in the endosperm, which is a special tissue used to nourish the embryo.
The Canadian lynx and the snowshoe hare have a predator-prey relationship. You will use two sets of population data and present them in a single graph.
Using the second picture below,label the x-axis ‘‘Year of Study’’.Label the x-axis with data listed in the first picture.(pls make sure that the grid your using is same as picture two below)
Based on the sizes of the numbers for each population, create a scale on the two separate y-axes. The snowshoe hare population ranges in size from 5000 to 95000. Label the y-axis on the left side of the x-axis as “Hare population (in thousands)." Number this y-axis from 0 to 100, in intervals of 10. The lynx population ranges in size from 500 to 6000. Label the y-axis on the right side of the x-axis as "Lynx population (in thousands)." Number this y-axis from 0 to 10, in intervals of 1.
Construct a line graph using the data from the first picture below.Use a different coloured like for each population.
Give your graph a title.Create a legend for your graph so it is easy to read.

d. Thr - Pro - Asn
Answer: A
Explanation:
UAC = Tyr
UCU = Ser
ACC = Thr
So the polypeptide chain corresponds to A
v-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins but are otherwise catalytically inactive. What do you think is the effect of v-FLIP expression in the host cell?A. It promotes apoptosis mainly via the extrinsic pathway.B. It inhibits the extrinsic pathway of apoptosis.C. It activates only the mitochondrial pathway of apoptosis.D. It inhibits the intrinsic pathway of apoptosis.E. It enhances the caspase cascades in both the intrinsic and extrinsic pathways.
Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
Goats are outside living on the sides of steep mountains. They are eating the
grass and bushes that grow there. It's a clear, sunny day on the mountainside.
What is happening to the carbon dioxide in the air? Is it ONLY being released (as a
product), ONLY absorbed (as a reactant), or being released AND absorbed?
CO2 is being both released by goats in exchange for O2 and absorbed by the plants in exchange for O2, too

A) Cattle ranchers have cut down trees to create space for their cattle.
B) A town has started getting their vegetables transported from far away.
C) A mine has burned down a forest to create room for buildings.
D) A town has started a new recycling and composting program.
Answer:
D
Explanation:
it just makes sense to me
Answer:
A town has started a new recycling and compost program.
Explanation:
Protecting earths resources, would not be by cutting down trees, burning down a forest( trees), getting vegetables from far away pollutes the car with the way they transport; but recycling helps and protects our earth.

what kind of nucleic acid is found in retroviruses?
Answer:
A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA.
