Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
How do limiting factors control population growth?
Answer:With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases. With a negative relationship, population growth is limited at low densities and becomes less limited as it grows.

state the importance of calcium and zinc in our body
Answer:
Calcium is a mineral found in many foods. Almost all calcium is stored in bones and teeth to help make and keep them strong. Your body needs calcium to help muscles and blood vessels contract and expand, and to send messages through the nervous system. Calcium is also used to help release hormones and enzymes that affect almost every function in the human body.
Zinc, a mineral that people need to stay healthy, is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly. Zinc also helps wounds heal and is important for our ability to taste and smell. Zinc is found in a wide variety of foods, and is found in most multivitamin/mineral supplements.

Why are protists, plants, fungi, and animals classified into the same domain but into different kingdoms ?
They are the same domain because they are all Eukaryotes. They are different from each other because they are not all Multicellular.
Protists, plants, fungi, and animals are classified into the same domain but into different kingdoms, because they share certain characteristics but are completely different in other traits.
Protists, plants, fungi, and animals are eukaryotic organisms because all their cells have a cell nucleus and they have membrane-bound organelles.Protists are unicellular (single-celled) eukaryotes that generally live in water environments.Plants, fungi, and animals are multicellular and exhibit evolutionary differential features (e.g., cell wall).In conclusion, protists, plants, fungi, and animals are classified into the same domain but into different kingdoms, because they share certain characteristics but are completely different in other traits.

Explanation:
The manure pit has been emptied and Ted now has to enter the manure pit to perform some maintenance work. He is hooked up to a lifeline and his colleague Sam is outside the pit ready to assist should a rescue become necessary. Do you notice any issues in this scenario?
The pit if empty so there is no need for additional precautions
Ted is wearing a lifeline so there is no need for additional precautions
Sam should be wearing a self-contained breathing apparatus
Ted should be wearing a self-contained breathing apparatus
Answer:
D. Ted should be wearing a self-contained breathing apparatus
Explanation:
According to this question, Ted has entered into an empty pit in order to do some maintenance work and his colleague, Sam, is outside the pit ready to assist him in case of emergency.
It is necessary to take additional precautions even if Ted is tied to a lifeline or the pit is empty. However, the additional precaution should be that Ted should be wearing a self-contained breathing apparatus (SCBA) in case of breathing or respiratory problems down the pit.

How can individuals help to conserve the resources in the picture?
Lipids, carbohydrates, and DNA all exist in human cells as long molecular chains. Which of the following describes how DNA differs from lipids and carbohydrates?
A. Only DNA has carbon Atoms
B. Only DNA is found in the cytoplasm
C. Only DNA is needed to create new cells
D. Only DNA contains genetic information
Answer:
D. Only DNA contains genetic information
Explanation:
DNA has the main function of carrying genetic information.
On the other hand, lipids and carbohydrates have the main functions of being energy sources.
Lipids are used for long term energy storage, while carbohydrates are used for quick energy.
DNA is different from lipids and carbohydrates because it contains genetic information, while the others don't.
So, the correct answer is D. Only DNA contains genetic information

Two samples of radioactive material from the same rock is prepared for testing. Sample A is cut into a 2 inch cube. Sample B is crushed into a fine powder. Compared to the half-life of the material in Sample A, the half-life of the material in the powdered Sample B is:
Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.

Primacy Producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.
Explanation:
Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.

Jupiter's Great Red Spot is believed to be ____________.
a. a volcanic area
b. the effect of a mountain system on Jupiter's wind system
c. a zone of high ammonia concentration
d. a large rotating hurricane-like storm (cyclone)
e. none of these
The Great Red Spot, a permanent region of high pressure in Jupiter's atmosphere, is responsible for producing the largest anticyclonic storm in the Solar System. Thus, option D is correct.
What Jupiter's Great Red Spot rotating hurricane-like storm?In Jupiter's atmosphere, there is a huge, rotating storm known as the Great Red Spot. It is similar to an Earthly hurricane, but considerably bigger.
The Great Red Spot on Jupiter is larger than Earth by more than two times! Within this storm, winds can gust as high as 270 miles per hour (ca. 435 km/h).
When astronomers first focused their telescopes on Jupiter in the 17th century, they discovered a striking reddish patch on the massive planet. More than 300 years later, the Great Red Spot is still visible in Jupiter's atmosphere. It is now understood to be a big storm that is rotating like a cyclone.
Therefore, Jupiter's Great Red Spot is believed to be (a large rotating hurricane-like storm (cyclone)).

Ryland is setting up a cooler to store flowers for a big event. Which of the following is NOT going to contribute to ethylene build up in his cooler?
O Gas leaks
O Succulents and cacti
O Old flowers
O Ripening fruit
Answer:
Gas leaks
Explanation:
I don't know anything about biology but I know gas leaks aren't good for plants
The option that will not contribute to ethylene building up in Ryland's cooler would be gas leaks.
Ethylene plant hormoneEthylene is an important hormone for plants that regulate processes such as leaf/fruit abscission, fruit ripening, and senescence.
Thus, keeping succulents and cacti, old flowers, and ripening fruit in the cooler would be a good recipe for ethylene building up in the cooler.
Gas leaks may not find its way into the cooler as long as it is closed.
