Estimate the number of cells that belong to each phase of the cell cycle the. Explain how you made your decision and describe what occurs at each phase of mitosis
Answer:
There are two ways to do this. You could actually learn the phases and count each one. Since you're posting here, it's a safe bet you have no intention of actually learning the material. The second is to estimate based on the total number of cells. At any given time, you will have approximately the following percentages for each phase of the cell cycle:
Interphase - 96%
Prophase - 2.5%
Metaphase - .5%
Anaphase - .5%
Telophase - .5%
In the picture, there are about 120 cells. Now you have to do a little 5th grade math to calculate the approximate mumbers of each phase. So, for Interphase, we multiply 120 x .96 = 115. For Prophase we multiply 120 x .025 = 3. For Metaphase, Anaphase, and Telophase, we multiply 120 x .005 = .6, which rounds up to 1 each. Now, as I specified, these numbers are approximate. Looking at the picture, I count three that are in Metaphase, two that are in Anaphase, and at least three in Telophase. And there are more than three in Prophase. The best way to figure this out is to print the picture and, using a guide from the internet, count the cells in each phase, marking them off as you count them so that you don't recount them. Good Luck!

Explain briefly George Wofan's hypothesis about the origin of the earth.
Answer:
In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.
Explanation:
In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.
According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.
Any two geological Era are as follows:
Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.
Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.
Thirteen different SSR loci are used by the FBI to perform DNA fingerprinting. If SNP loci were assayed instead to identify individuals, which of the following would be true?
a. Fewer than 13 SNP loci would need to be assayed.
b. Many more than 13 SNP loci would need to be assayed.
c. All SNP loci could be genotyped, just as all SSRS are, by electrophoresis of a PCR product.
d. SNP loci, because they are usually biallelic, cannot be used to identify individuals.
e. Using SNPs instead of SSRs, only carriers of disease alleles could be identified.
f. Using SNPs instead of SSRs, only non-anonymous SNP loci could be assayed.

What is DNA fingerprinting?The technique of identifying a person's DNA traits is called DNA profiling. DNA barcoding is a type of DNA analysis used to identify species rather than specific individuals. The nucleotide sequences of specific areas of human DNA that are particular to each person are utilized in the laboratory procedure known as DNA fingerprinting to ascertain a person's likely identification.
DNA fingerprinting is a method for detecting and analysing individual DNA variations. It is based on polymorphism and variability in DNA sequences. Applications of it include: It is utilized in forensic science to pinpoint potential criminal offenders. to establish family relationships and establish paternity.

What does it mean if the allele frequency in a population consistently changes?
A. The population is stagnant.
B. The amount of alleles available is growing.
C. The amount of alleles available is shrinking.
D. The population is evolving.
Answer:
d
Explanation:
the population is evolving
Allele frequency is the probability of the gene in a particular population. The consistently changing allele frequency in a population depicts the process of evolution. Thus, option D is correct.
What is evolution?Evolution is the modification in the transitional or the expansion of the inherited characters passed from the parent to the offspring and successive generations over time through reproductive methods.
The allele or the gene frequency defines the evolutionary pattern as the alleles carry and express the characteristics that were passed. Due to environmental changes, the alleles can get modified for better adaptation.
This adaptation and natural selection allow the organism to evolve from the pre-existing species to adapt and with better traits that enable their survival.
Therefore, option D. the changing frequency depicts the evolving population.

The backbone vertebrae, skull, and rib cage make up the _______ skeleton. Among other types of cells, bone marrow produces _______ blood cells, which carry oxygen in the blood. _______ can eventually become osteocytes. If bones rapidly deconstruct faster than new bone tissue grows, this can lead to less dense and more fragile bones. When severe, this condition is called _______. _______ such as the MCL and ACL connect bone to other bone at joints.
Answers :
axial

Osteoblasts
osteoporosis
Ligaments
Osteoblasts are cells that build bone tissue, and are called osteocytes when they become surrounded by the bone that they have built. Osteoclasts are cells that break down bone tissue. The building and breaking down of bone tissue continues throughout a person’s lifetime and makes bones strong. If osteoclasts break down more bone than osteoblasts build, this can lead to osteopenia and osteoporosis, causing bones to be fragile and break more easily.
Answer:
1. axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
Explanation:
The axial skeleton consists of the bones of the head and trunk of a vertebrate including skull, and rib cage.
Bone marrow produces red blood cells, which carry oxygen in the blood.
Osteoblasts can become osteocytes, which are the third type of bone cells.
Osteoporosis is a bone resorption disease in which bones rapidly deconstruct faster than new bone tissue grows, and decreases the mechanical strength of bones.
Ligaments connects one bone to other at joint such as medial collateral ligament (MCL) and anterior cruciate ligament (ACL) that joins knee.

Explanation:
Hydrogen has an atomic number of one but has no neutrons if a hydrogen atom has a mass of three it would be
Answer:
tritium
Explanation:
a hydrogen atom with:
1 proton 0 neutrons = hydrogen
1 proton 1 neutron = deuterium
1 proton 2 neutrons = tritium
If the hydrogen has a mass of three, then it would be tritium
What it would be?An atom of hydrogen with an atomic number of one and a mass of three would be a hydrogen isotope called tritium.
Regular hydrogen (also known as protium) has one proton and no neutrons, giving it a mass of approximately 1 atomic mass unit (amu). Tritium, on the other hand, has one proton and two neutrons, giving it a total mass of about 3 atomic mass units (amu). This makes tritium a heavier and less common isotope of hydrogen.
