Answer:The major parts of an ecosystem are: water, water temperature, plants, animals, air, light and soil. They all work together. If there isn't enough light or water or if the soil doesn't have the right nutrients, the plants will die.
Explanation:
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.
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.

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 climbing plant wraps around a lattice structure as it grows. This is an example of which type of tropism?
Answer: I believe it is Thigmotropism.
This is thigmotropism as it is responding to touch. Since the plant cannot support itself, it wraps around the lattice structure.
A low pressure system moves across an area. What kind of weather change do you think you can you expect

A trait that occurs in 900 individuals out of a total of 1,800 individuals occurs with a probability of
Answer: 0.5
Explanation:
Number of people with traits = 900
Total number of individuals= 1800
To find the probability with regards to the question, we divide the number of individuals having the traits by the total population of individuals. This will be:
= 900 / 1800
= 0.5

CAN YOU PLZ ANSWER AND STOP WASTING MY POINT NOT TO BE RUDE... i will give brain whatever it calls just answer
Its apocrine glands. Please give me brainliest?
I really need 1-4 pleaseeee
Answer:
Answer below!
Explanation:
1. Genotypic ratio: 1 : 1 ( GG = 50%, Gg = 50% )
Phenotypic ratio: 1 : 0 ( Since the dominant trait always shows, the plant would only exhibit trait G, green pods = 100 % )
2. Genotypic ratio: 1 : 1 ( Rr = 50%, rr = 50% )
Phenotypic ratio: 1 : 1 ( Oval shell = 50%, round shell = 50% )
3. Genotypic ratio: 1 : 0 ( ss = 100% )
Phenotypic ratio: 1 : 0 ( short tooth = 100% )
4. Genotypic ratio: 1 : 0 ( Bb = 100% )
Phenotypic ratio: 1 : 0 ( brown eyed = 100% )
Hope this helps, good luck!
can someone please help me on how to do this thing it is not hard i just don't get how to answer it
What types of plants live in your biome? Describe the adaptations that help the plant survive in the biome. (Give 5 examples of each)
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.

What is inside an animal cell?
Answer:
Nucleus, vaculoe, cytoplasm, cell membrane
thats all I can remember
Answer:
Nucleus,cytoplasm, endoplasmic reticullum,ribosome,mitochondria,Gollgi complex,Vacoule and lysosome.
Explanation:
Nucleus - controls cell activities, contains the DNA for the cell.
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 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.

What is an example of a community protecting Earth's resources?
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.

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.

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
Explanation:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.
