Answer: usually from carbs
Explanation:
We should note that the function of the ATP molecule is simply for the storage of energy. In a case whereby the ATP molecule loses a phosphate group, energy is being released from it which is used for cellular processes.
Our body get the energy for reattaching a third phosphate to ADP, creating ATP usually from carbs. Therefore, the correct option is B.

As the nutritional energy passes through the food chain, energy......
O a) is gained
b) decreases
c) remains constant
d) increases, then decreases
Answer:
B. Decreases
Explanation:
In an ideal food chain, nutritional energy from producers (plants) are transfered to other animals at different levels on the food chain. As nutritional level is being passed from one level to another, most of the nutritional energy is lost in the process. Therefore, energy decreases as the nutritional energy passes through the food chain.
explain how environmental factors affect the rate of transpiration in flowering plants
Explanation:
there are a couple of environmental factors that affect the rate of transpiration. they include:
I) wind:in a windy environment there is easy movement of moisture hence it does not accumulate on the leaf surface. this helps to increase diffusion gradient between the intercellular spaces in the leaf and in the environment there4 the rate of transpiration is increased. in a calm environment moisture accumulates on the surface of a leaf there4 reducing the diffusion gradient there4 reducing the rate of transpiration
ii) atmospheric pressure :in low lands there is high atmospheric pressure than in the highlands. the more the atmospheric pressure the more the pressure exerted on the cells of the leaves there4 reducing the rate of transpiration.
iii) humidity:the more the humidity in the atmosphere the less the rate of transpiration. this is due to low diffusion gradient due to accumulation of water vapour on the surface of the leaf
iv) temperature:a rise in temp increases the water vapour holding capacity of air in the air spaces within the spongy mesophyll layer. the water vapor pressure in the intercellular spaces increases causing an increase in diffusion gradient between the intercellular spaces and the environment there4 increasing the rate of transpiration. decrease in temp decreases the water vapor holding capacity in the intercellular spaces there4 diffusion gradient is lowered there4 reducing the rate of transpiration.

What is phylogenic tree?
A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
What can phylogenetic trees tell us?
A phylogenetic tree can help trace a species back through evolutionary history, down the branches of the tree, and locate their common ancestry along the way.

After comparing the original double helix on the right, the errors with the replication if they occurred and nitrogen bases are not the same in the same space and there is no urical.
What generally occurs at the time of DNA replication?Errors occurs mainly at the time of DNA replication. Mutations has been refers to the changes in the DNA sequence made at the time of DNA replication, thus, the DNA replication procedure has possesses characteristics that has minimize mutations.
The three small scale of the mutations, which can take place at the time of the DNA replication which are nucleotide substiution, inversion as well as translocation.
Eukaryotic chromosomes have often multiple origins of replication. Given the size of the eukaryotic chromosomes, this has been necessary for full reproduction to occur on time. Each of these origins defines the replica, or DNA sequence, that reproduces from a particular origin. The copies do not reproduce at the same time, so care must be taken to ensure that the copies are used only once during the cell cycle.
Therefore, After comparing the original double helix on the right, the errors with the replication if they occurred and nitrogen bases are not the same in the same space and there is no urical.

Most successful parasites, such as a cat flea, weaken their host but do not kill it. Why is killing its host usually disadvantageous for a parasite?
Question 4 options:
Relatives of the host would then attack the parasites.
Lysosomes from the host would then attack the parasite.
If a parasite kills its host, it will then have to find a new host in order to survive.
Parasitism is a relationship where both organisms benefit; killing the host is not beneficial to the host.
Answer:
The correct answer is - If a parasite kills its host, it will then have to find a new host in order to survive.
Explanation:
Parasites are organisms that depend on other organisms for their food and energy in order to survive. The organism that they depend on is called their host. In this only parasites get benefitted while hosts are harmed.
Although parasites harm their hosts, parasites tend to not kill the host as its best for them so they do not have to find another host and again establish control on the host's body and body functions, for their survival.
