Answer: All organisms need energy. ...
Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. ...
Heterotrophs (consumers) obtain energy by consuming other organisms. ...
The flow of energy in an ecosystem can be represented with a food chain or food web
Explanation: A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. A consumer is an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources. Consumers are also called heterotrophs, or other-feeders Producers
Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react 4these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.
4. Cross a white bull with a white cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow
Answer:
100% white cow
Explanation:
This question involves a single gene coding for skin color in cattle. The allele for red color (R) is codominant with the allele for white color (r). Hence, the roan cattle (Rr) will possess both red and white coloration.
According to this question, a white bull (rr) is crossed with a white cow (rr). Each parent will produce the "r" gamete, which when used in a punnet square will produce all WHITE COWS i.e 100% white cows. See punnet square attached.
Answer:
white cow
Explanation:

why is there a need to protct our forests coral reefs and mangrove swamps?
Answer:
If we don't protect our forests, they get either get burned or cut down so that people can build more places or more space for crops. If we have little forest, there will be little oxygen in the air and we will die, global warming will also increase. Coral reefs are meant to protect the sea from inhumane acts which pollute the sea and cause marine animals to die, if they die the sea will be very polluted and marine animals might become extinct. Mangrove swamps are a habitat to many different animals, if they are gone the animals will have no habitat to live in and might soon face the consequences of extinction.

Is meiosis sexual reproduction or asexual?
Answer:
Sexual reproduction
Answer:
Meiosis is sexual reproduction.
Explanation:
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

Explanation:
Animals release _____ into the atmosphere through _____
Answer:
animal release carbon dioxide into the atmosphere through respiration
Explanation:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.
Animals breathe, taking in oxygen and releasing carbon dioxide. Animals release carbon dioxide gas into the outer atmosphere through respiration process.
What is respiration?
This process completes in two steps: external respiration and internal respiration. External respiration, or breathing, includes inhaling (inhalation) oxygen from the outside atmosphere and exhaling (exhalation) carbon dioxide to outside. In this process, gas exchanges take place at the lungs, and deoxygenated blood oxygenates before going back to the left heart.
In cellular respiration, the cell takes oxygen from the oxygenated blood and uses it in different cellular metabolic reactions, releasing carbon dioxide into the blood. So in cellular respiration, oxygen is taken up by the cell and carbon dioxide is released by the cell. This carbon dioxide goes to the lungs, and by the process of exhalation, it is released into the atmosphere.
Hence, animals release carbon dioxide into the atmosphere through the respiration process.

what is significance of crossing over during meiosis?
Answer:
A- a different combination of genes is provided to each gamete
Explanation:
Crossing over accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical

The ____________________ endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.
Answer:
The rough endoplasmic reticulum works with the Golgi apparatus to move new proteins to their proper destinations in the cell. The membrane of the RER is continuous with the outer layer of the nuclear envelope. Smooth endoplasmic reticulum does not have any ribosomes attached to it, and so it has a smooth appearance.
Explanation:
The rough endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.
What is Protein transporting?Protein transporting may be defined as a process through which proteins are transported from one cellular organelle to another after being synthesized in the rough endoplasmic reticulum along with the Golgi complex.
Due to having ribosomes on their surface, the rough endoplasmic reticulum is known as the site of protein synthesis. Due to the presence of ribosomes, their surface is not as smooth as compared to the smooth endoplasmic reticulum.
The protein after synthesis packed into the spherical-shaped vesicles which are then fused with the membrane of a specific cell organelle in order to function properly.
Therefore, the rough endoplasmic reticulum has a role in transporting proteins to different compartments in the cell.

First question: When the population of lynx increases, the population of hares will decrease due to being over-hunted by more predators than usual. The hare is a source of food to the lynx, so with more lynx's...less hares... and less hares means either less food for the lynx and their population starts to die off...OR... The lynx adapt and start hunting new animals which could cause a massive disruption in the food chain.
Second question: When the number of hares increase in the environment it would mean more food for the lynx and other predatory animals. But with more food, comes more overpopulation. with plenty to eat the lynx population increases and that could cause problems for the environment, and other creatures.
