Answer:
The lack of Mad1 protein can cause faster cell division.
Explanation:
The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.
Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.
The cell cycle is the division of cells and the replication of the genetic material. The cell cycle requires 24 hours to complete the cell cycle, whereas some animals complete the cell cycle in 9-10 hours due to a lack of Mad1 proteins.
The correct answer is:
Lack of Mad1 proteins.
The function of Mad1 proteins are:
Mad 1 proteins regulate the attachment of chromosomes to the spindle microtubules. The proteins halt the cell cycle in the anaphase until the spindle apparatus is formed.The lack of protein in the other organisms causes rapid cell division. The protein is a checkpoint and arrests the cell cycle in anaphase, however, the lack of these proteins will cause a faster cell cycle.
Therefore, lack of Mad1 proteins will result in a faster division, because no checkpoint will be available in the anaphase of the cell cycle.

True
False
Answer:
True
Explanation:
This statement is true. The temple ruins at Pozzuoli that is located in Italy have displayed rapid rises and falls, relative to sea level and no sea-level changes have in the past 500 years when it comes to that. Sea level rise can be tracked nowadays and people can see if the sea level is rising at the time or not.

Is hemoglobin a hormone?
Answer:
I'm really sorry it is not.
A new hormone called erythroferrone, which regulates the iron supply needed for red blood-cell production, has been discovered by researchers. Iron is an essential functional component of hemoglobin.
Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the "building blocks" of proteins.

Explanation:
Most igneous activity takes place?
Answer:
under the ground in volcanoes
Explanation:
There are some volcanically active spots that are in the middle of a tectonic plate.
The interior of the Earth is hot, while the surface or crust of the planet is cold. Between these layers are areas of molten rock. These molten rocks are less dense, so they easily break through cracks in the Earth's crust.
Magma is molten rock and is found beneath Korea. Beneath the volcano, in the underground spaces, magma accumulates.

In what way do two alleles for the some trait differ?
A. The are found on different chromosomes.
B. They consist of different sequences of DNA
C. They are produced by two different people.
D. They are complementary.
Answer:
B. They consist of different sequences of DNA
Explanation:
Alleles are contrasting or alternative forms of a gene. A diploid organism i.e an organism with two sets of homologous chromosome, contains two alleles for each gene that encodes a trait. Although the two alleles of that particular gene encodes the same trait, they can encode different phenotypes i.e way it is expressed because they contain different sequences of DNA.
For example, in a gene coding for height in pea plants, two alleles, T and t are responsible. Allele T codes for tall height (phenotype) while allele t codes for short height (phenotype). Although the two alleles are for the same trait, they differ in the content of their DNA sequence, hence, are expressed differently or variably.

If a gene has two alleles, and allele A has a frequency of 83 percent, then allele a has a frequency of:_______
Answer:
Another allele frequency = 17%
Explanation:
Given:
Allele A has a frequency = 83 percent
Find:
Another allele frequency
Computation:
Sum of percent = 100%
So,
Another allele frequency = 100% - 83%
Another allele frequency = 17%

Answer:
Importance of building specie database, for restoration projects.
Explanation:
Restoration implies human intervention, for renewing - degraded ecosystems & habitats.
Building species data base is important for this, as - wildlife is an integral part of habitat. Understanding their favourable living ambience in ecosystem - like temperature, humidity, sunlight & water access and migration patterns is important - in effort to restore environment in real sense.

In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
Glucose + Oxygen ------> ATP + Carbon dioxide + Water
C6H12O6 + 6O2 ----------> 36ATP + CO2 + H2O
The chemical equation for cellular respiration shows that plants cycle matter because oxygen and glucose that is produced by the plants is used by the human body for the generation of energy in the form of ATP molecules, water and carbondioxide gas.
This carbondioxide gas is released by animals which is used by the plants in order to make their own food during the process of photosynthesis so we can conclude that the chemical equation for cellular respiration shows that the plants cycle matter.

Which layer of soil contains large rocks that have not been weathered yet?
A. Topsoil
B. Dirt
C. Bedrock
Answer: Option C.
Bedrock
Explanation:
Bedrock consist of hard rock that has not been weathered because bedrock is the hard rock that is found under surface materials like soil and are components of quartzite, limestone , basalt and granite. It is a solid and it is bound very tight. It also form parent rock and it can remain on the top of the soil which later weathered and form soil and can be taken away by wind, water, gravity e.t.c.
