Answers

Answer 1
Answer: In metaphase 1, the chromosomes are arranged on the metaphase plate and are attached onto the spindle fibers. They are in the middle of the cell and are pulled by the the spindle fibers.
Hope this helps.

Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history. 2 phylogenetic trees are shown. The first tree has 3 branches that go to duck, platypus, and opossum. The second tree has 2 branches that go to duck and platypus. Opossum branches off of the platypus branch. Which can be concluded from a comparison of the two phylogenetic trees?

Which activity can occur without the use ofenergy?
(1) contraction of muscle tissue
(2) protein synthesis in a cell
(3) active transport of minerals
(4) movement of water across a membrane

Answers

Answer;

-Movement of water across a membrane

Explanation;

-Movement of water molecules across a membrane is an example of passive transport . Passive transport involves movement of ions and other atomic or molecular substances across cell membranes without need of energy input.

-Unlike active transport, passive transport does not require an input of cellular energy (ATP). Examples of types of passive transport are osmosis and diffusion.

Speciation is the formation of new species as result of evolution by natural selection. What effect could separation of populations have on speciation? A) one half of the species will go extinct if the population is separated
B) the separation populations will always evolve into at least 2 different species
C)if the environments differ enough, the separated populations may evolve differently
D) by separating, the populations will no longer be able to interbreed and will die off

Answers

Animals pass down their features to their children when they breed.  When you separate a population (or group of animals of the same species), say by building a large wall, they can't interbreed with each other.  This means that if an animal on one side of the border gets an adaptation, it won't pass it on to the other animal.  Soon, each side will evolve different adaptations, and the two populations will become so different that they become two different species.

It is possible that one-half wouldn't be able to survive, and go extinct, but it doesn't happen all the time (A is incorrect).  Similarly, the populations don't ALWAYS evolve into two different species, though they may (B is incorrect).  However, if the environments differ enough, they will acquire different adaptations through evolution.  C is correct!  Keep in mind that D is incorrect: the first part, the populations can't interbreed, is correct, but that doesn't mean they will die off.

How do plants obtain carbon atoms? a. from carbon in the soil
b. from microorganisms that live in soil
c. from carbon dioxide in the atmosphere
d. from animals that feed on the plants

Answers

the answer is C:  FROM CARBON DIOXIDE IN THE ATMOSPHERE

The answer is C: From carbon dioxide in the atmosphere! It's because when we breathe in the oxygen that the plants produce we breathe out carbon dioxide and the plants kinda do the same thing just instead of breathing in oxygen they breathe in carbon dioxide and breathe out oxygen!
