List at least three differences between the cells of the palisade mesophyll.
Answer:
1. The palisade mesophyll has long cylinder-shaped cells,
2. Lots of chloroplasts, cells closely packed together
3. The large size of cells.
Explanation:
The mesophyll is the soft internal parenchyma of a leaf. There are two types of mesophyll cells: Palisade mesophyll cells and spongy mesophyll cells. Palisade mesophyll cells are located directly under the epidermal cells of the adaxial leaf blade surface.
The palisade mesophyll layer is where most photosynthesis occurs in the leaf.The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis.The palisade cells are closely packed together to maximize light absorption.Thus, Three differences between the cells of the palisade mesophyll and the cells that make up the other areas within the leaf -

If pregnancy among women does not occur, then menstruation occurs. The menstrual cycle usually lasts about 28 days.
What do women experience during their menstrual period?During menstruation, women may experience abdominal cramps, headaches, backache, and nausea.
The stage in which a woman is most fertile is called Ovulation. During this step, an egg is released from the follicle in the ovaries.
If a fertilized egg successfully embeds itself in the uterine lining, then the woman becomes pregnant.
If the fertilized egg does not manage to embed in the uterine lining, then menstruation will occur.
The two main hormones that control the menstrual cycle are estrogen and progesterone. If the egg is not fertilized, then progesterone levels drop.
The estrogen needs to stop FSH to be produced to make sure only one egg matures in the cycle.

In which phase of mitosis does DNA replicate? Question 3 options: Interphase Prophase Metaphase Anaphase Telophase.
Answer:
Interphase
Explanation:
At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division. The cell grows at a steady rate throughout interphase, with most dividing cells doubling in size between one mitosis and the next.

Is every human body built exactly the same anatomically?.
Answer: Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences.
Explanation: An example is the heart's circulatory system, where the vessel supplying blood to the posterior part, known as posterior descendant artery, stems from the right coronary artery in 80-85% of the cases, and from the left coronary artery in the remaining 15-20%. This is known as either right of left dominance
How is the carrying capacity related to the limiting factors of a population?
Answer:
The maximum population size that an ecosystem can support is called carrying capacity. Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem

Explanation:
i got it wrong then it showed me the right answers, you're welcome.
Its relative, the bullfrog, breeds in permanent ponds from late March through May. the mechanism of isolation include Temporal isolation 2. Geographic isolation 3. Behavioral isolation
what are the different types of isolation ?Isolation is the process in which two species produce hybrid offspring and there are five major isolation processes which prevent two species from interbreeding.
Ecological, or habitat isolation which occur when two species interbreed because the species live in different areas; Temporal isolation occur when species could interbreed do not because the different species breed at different times.
This temporal difference are difference times of day, different times of the year, or anything in between; Behavioral isolation occur due to the fact that many species perform different mating rituals.
Mechanical isolation occur by structures or chemical barriers that keep species isolated from one another; Geographical isolation refers to the physical barriers which exist that keep two species from mating

Why did finding Mesosaurus fossils in South America and Africa support the hypothesis of continental drift?
F. Mesosaurus could only have ended fossilized on both continents if they were once together.
G. Mesosaurus was unable to swim across oceans, so the fact that its fossils were found on distant continents suggested those continents had once been fused together and later moved apart.
H. Mesosaurus is now found in colder parts of the world, which means the continents have drifted since the fossils were made.
I. Mesosaurus wasn't found in Asia, which Wegener thought was the only stable continent that hadn't moved.
Answer:
G
Explanation:
it is pretty self explanatory but its either G or F.
