Answer:
Metaphase.
In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles.
All organisms have the same feedback mechanisms that help them maintain homeostasis.
true/false
Answer:
True
Explanation:
Do all living organisms have mechanisms for homeostasis?
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity.
Why are food chains limited in how long they can be?
plss help
Answer:
Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body. However, these transfers are inefficient, and this inefficiency limits the length of food chains.

How is cross pollination carried out in nature?
A, B, or C?
OPTION B is the correct answer
Cross-pollination is carried out by bees and other pollinators, which is present in option B, as cross-pollination is a process in which pollen from the male reproductive organs of a plant (such as the stamen) is transferred to the female reproductive organs.
Cross-pollination is facilitated by various agents, including insects, birds, wind, and even water. These agents inadvertently carry pollen from one plant to another as they move between flowers or plants. Insect pollinators, such as bees, butterflies, and beetles, are the most common and efficient carriers of pollen in cross-pollination. They visit flowers to obtain nectar or pollen as a food source, and in the process, pollen grains get attached to their bodies and are transported to other flowers.

What two forms of energy are produced by nuclear fusion?
Answer:
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.

6. The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles,
and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local
ecosystems?
A. The variety of interactions among the different species helps the ecosystems remain
sustainable.
B. The variety of interactions among the different species prevents the ecosystems from being
sustainable.
C. The uniformity of interactions among the different species prevents the ecosystems from
being sustainable.
D. The uniformity of interactions among the different species helps the ecosystems remain
sustainable.
Answer:
A.
Explanation:
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

Answer:
There is no way to produce tall offspring since both parents are homo-zygous recessive.
Explanation:
parent plants are short because neither of them has at least one dominant "S" gene. As both of them have recessive "s" genes, they are scientifically known as homo-zygous recessive organisms. So produced offspring will never be tall as they don't have the dominant "S" gene transmitted from their parents. this is genotypically expressed as below.

The two strands that make up the DNA double helix are said to be antiparallel. What does that mean?
Nucleotides containing adenine base pair with nucleotides containing thymine.
The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
Base pairings create unequal spacing between the two DNA strands.
Answer:
The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.
Explanation:
Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

The cell membrane's function is to..
O allow nutrients in, and send wastes out of the cell
O to control the amount of water that enters the cell
O to block all nutrients from entering the cell
Answer:
The first bullet point is correct
Explanation:
The cell membrane controls what comes in and out of the cell, it needs minerals so would not block them completely, and water does not enter cells so it is clearly the first one.
Write the complementary strand to this DNA molecule on the line.
G А Т
ССА TG A G TT A CG
Answer:
If you mean the complementary strand of GAT: Answer is CTA
If you mean the strand for all of it (GATCCATGAGTTACG): Answer is CTAGGTACTCAATGC
Explanation:
Both strands always have to be in a sequence that pairs them to their nitrogenous base pair according to Chargaff's law. So always remember:
A pairs with T (Adenine with Thymine)
C pairs with G (Cytosine with Guanine)
Whenever you need to figure out the other strand, just switch the original base sequence with their base pairs to get the second strand/sequence.
