e of mitosis and meiosis?
Biology

ANTONII [103]3 years ago
4 0

Answer:

<h2>In mitosis, the DNA replication occurs in S phase , so the amount of DNA increases in S phase and remain double until cell division( karyiokinesis).</h2><h2>Meiosis 1 is reductional division and meiosis 2 in equational division.</h2><h2>after meiosis the number of chromosome  and DNA become half.</h2>

Explanation:

Mitosis: interphase ( G1, S,and G2) and mitotic phase ( prophase, metaphse, anaphase ,telophase)

c= chromose number ,N = DNA  amount

In mitosis, the chromosome number remains same until anaphase, so the number of chromosome become doubles in anaphase and telophase.

In mitosis, the DNA replication occurs in S phase , so the amount of DNA increases in S phase and remain double until cell division( karyiokinesis).

meiosis  ; Meiosis 1 and Meiosis 2,

Meiosis 1 is reductional division and meiosis 2 in equational division.

after meiosis the number of chromosome  and DNA become half.

In which type of rock would you find a large amount of silica?
____ [38]

Answer:

igneous

Explanation:

Igneous rock is the type of rock that contains a large amount of silica. Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Silica is a common component of magma, so igneous rocks are often rich in silica. Glass, which is also made from silica, is not a type of rock. Metamorphic and sedimentary rocks are formed through processes that do not involve the melting of rock, so they typically contain lower amounts of silica.

Scientists can find new discoveries that change their current understanding of scientific knowledge.
Dahasolnce [82]
I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)

Which description properly describes the plant structures involved in photosynthesis?<br><br>​
Nonamiya [84]

Answer:

C Phloem transports glucose to the plant, and stomata release oxygen

Explanation:

A Stomata take in water,sunlight, and carbon dioxide and release oxygen  - this is false, the stomata are for gas exchange (taking in carbon dioxide and releasing oxygen). They do not take in water and sunlight

B Phloem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight - this is false, while it is true that stomata take in carbon dioxide, and chlorophyll absorbs sunlight. phloem does not transport water, that is the xylem.

C Phloem transports glucose to the plant, and stomata release oxygen - this is true. Stomata takes in carbon dioxide and releases oxygen, and phloem transport the products of photosynthesis throughout the plant

D Xylem takes in water, sunlight and carbon dioxide and releases oxygen - this is false. Xylem does take in water, but not sunlight, carbon dioxide or oxygen

How to get high affinity antibody?
Anit [1.1K]

Human monoclonal antibody (mAbs) are emerging in the field of cancer therapy and have become an increasing proportion of new drugs that are recently approved. Although there are some methods to obtain antigen-specific mAbs from human B cells, it is generally impossible to directly immunize human beings with antigens of interest. For example, for infectious agents, those approaches are largely restricted. To solve these obstacles, two main approaches have been developed; either by humanizing antigen-specific antibodies from small experimental animals (which is laborious due to the great genetic differences from humans) or rely on the in vitro selection of antigen-specific binders from human antibody repertoires. However, the human mAbs developed by these methods are usually with low affinity.

We are now coming up with a much better idea that is humanizing non-human primates mAbs instead of murine mAbs. Due to the close genetic relationship with humans, immunized NHPs have more potential to be isolated with high affinity antibody to human target than other experimental species, such as mouse, rat and rabbit. In addition, with appropriate method, NHP antibodies are much<span> easier to be humanized</span> without any loss of affinity compared to widely used murine antibodies.
