Question: A scientist is studying fruit fly wings. Straight wings are dominant, and curly wings are recessive. Which statement correctly describes the F1 generation if a straight-winged parent is crossed with a curly-winged parent and if both parents are true breeding?

Answer choices:

1. The offspring will have two genes for straight wings.

2. The offspring will produce only gametes that have genes for curly wings.

3. The offspring will have one allele for straight wings and one allele for curly wings.

4. The offspring will have only one kind of allele for the gene that determines wing type.

Correct answer: The offspring will have one allele for straight wings and one allele for curly wings.

AA + aa = Aa

Natali5045456 [20]

Answer:

1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.

3. Its parasitic since the mistletoe just takes and takes harmfully

What is the primary purpose of each (A) membrane channels (b) membrane pumps?
crimeas [40]

According to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

<h3>What are membrane channels and pumps?</h3>

They are pores in the cell membrane through which ions circulate for muscle contraction or membrane potential changes that may depend on a ligand or voltage, depending on whether their opening is determined by the binding of a ligand or by changes of voltage.

In this sense, membrane pumps is the mechanism of active ion transport, consuming energy across a membrane against an electromechanical gradient to maintain differences in ion concentration between the intracellular and extracellular space.

Therefore, we can conclude that according to the research,  the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

40 POINTS!! Please give me an explanation of how energy and matter is being conserved in an amazon rainforest.
Murrr4er [49]

Explanation:

The Amazon Rainforest is an incredibly complex ecosystem. The unique conditions of an almost constant temperature and a high, regular precipitation rate are what allow the incredible amount of biodiversity to occur there. Because of its size and high rate of productivity, the Amazon Rainforest ecosystem plays a substantial role in many of the biogeochemical cycles of the world.
