Answer:
The point at G1 at which commitment occurs and the cell no longer requires growth factors to complete the cell cycle has been termed the restriction (R) point. The R point has been temporally mapped at 2–3 hours prior to the onset of DNA synthesis.
Explain in your own words why a fulcrum is necessary for a lever to work.
Answer:
The lever has two important parts. The lever itself and the fulcrum. The placement of the fulcrum determines how far the levered object will move, and how much force is required to move it. If a weight was resting on a lever a person could lift the weight by pressing on the lever on the other side.

how does a tape worm feed
Answer:
The tapeworm feeds off the food that the host is digesting.
Explanation:
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines.
Answer:
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument. New proglottids are constantly formed in the neck of the worm and along the length of the tapeworm they mature.
Explanation:
what is the relationship between working distance and field of view
Answer:
yeah
Explanation:
Field Of View (FOV): The Viewable area of the object under inspection. In other words, this is the portion of the object that fills the camera's sensor. Working Distance (WD): The distance from the front of the lens to the object under inspection. Resolution: The minimum feature size of the object under inspection.
why do you think diversity is important for the survival of a species?
Answer:
Genetic diversity refers to the amount of genetic variation within a species. Diversity is important for species survival as it provides a way for populations to adapt to changing environments with more variation. More individuals within a population will possess allele variations that are suited to the environment and they will survive more effectively.

Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water
•more slowly
•at the same rate
•more rapidly
Answer:
more rapidly
Explanation:
Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.
According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.
The DNA code for normal hemoglobin contains the following segment:
TGC-GGA-CTC-CTC
Which of these is the m-RNA code for this segment of DNA?
A) UGC-GGA-CUC-CUC
B) ACG-CCU-GAG-GAG
ACG-CCT-GGA-GAA
D) TCC-GGT-CTC-CTC
The messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).
What is mRNA?The messenger RNA (mRNA) is a template created during transcription, which is used to generate a protein.
A specific fragment of DNA is used to create this template (mRNA) by transcription.In RNA, Thymine nucleotide bases are replaced by Uracil nucleotide bases.In conclusion, the messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).

Which of the following was not advocated by the Black Panthers?
a
nonviolence techniques to achieve goals
b
the Black Power movement
c
black nationalism movements
d
community development efforts
Answer:
A.
Explanation:
The Black Panther Party was a political party formed by Huey P. Newton and Bobby Seale in 1966 in Oakland, California. The party was formed to protect the black community from police brutality. The operations advocated by the Black Panther Party were the Black Power Movement, the black nationalism movement, development efforts for the black community, and violent ways to achieve their goals.
Therefore, the way not adopted by the Black Panthers Party is option A, nonviolent ways to achieve their goals. In reality, Huey P. Newton was convicted of manslaughter for killing a police officer and was sentenced to 15 years imprisonment. Thus option A is correct.

A phylogenetic tree is also called the phylogeny. It's a diagram that shows the evolutionary relationships that can be found in various organisms.
A dichotomous key refers to a scientific tool that's used in the identification of different organisms based on the observable traits that can be found in the organism.
It should be noted that the phylogenetic tree and dichotomous key were founded by Carl Linneaus.

The peppered moth is a classic example of natural selection in the
environment. The peppered moth has three color patterns: light, medium,
and dark. Prior to the industrial revolution, the light moth, which could

industrialization, the darker moth population quickly increased since the
tree bark became darker. Which of the following BEST describes why the

Answer:
A cell
Explanation:
Answer:
cell
Explanation:
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

Write 5-6 sentences about snakes. (This is for an informational paper, make if formal!) Please don't put links/files to download because I can't download on this computer since it is the family computer. THANK YOU!
Answer:
Hi, I can help you!
Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[
