3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)

Explanation:

For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them.  The first three letters of the amino acid are the abbreviation.

Austin made the claim that meiosis provides an advantage for sexually reproducing organisms by ensuring genetic variation

Which statement explains why he is correct

A. Meiosis allows the offspring produced during sexual reproduction to grow and develop

B meiosis joins together the sex cell during sexual reproduction to produce new offspring

C meiosis produces sex cells that are joined during sexual reproduction to produce offspring

D meiosis produces the body cells that join to form new offspring during sexual reproduction

Answers

Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring

Explanation:

Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.

1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.

2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.

3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?

Answers

Answer:

RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.

These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.

The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.

Answers

The first phase of mitosis is prophase where DNA condenses down into chromosomes and the duplicated separate. The second phase of mitosis is metaphase where sister chromatids line up on the cell plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the centrosome. The third phase of mitosis is anaphase where sister chromatids or homologous chromosomes are pulled apart. The fourth phase of mitosis is telophase where the nuclear membrane starts to reform and the DNA de-condenses.

MITOSIS:

This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc.

PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.

METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME.

ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles.

The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.

It is estimated that the world human population reached 3 billion people in 1959 and 6 billion in 1999. Assuming a carrying capacity of 16 billion humans, write and solve the differential equation for Gompertz growth, and determine what year the population reached 7 billion. Was logistic growth or Gompertz growth more accurate, considering world population reached 7 billion on October 31,2011

Answers

Answer:

i ) Gompertz equation :

[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]

ii) The year that population reaches 7 billion is 2013

iii) The logistic growth was more accurate

Explanation:

i) write and solve the differential equation for Gompertz growth

Gompertz equation :

[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]

∝ = growth rate

k ( carrying capacity ) = 16 * 10^9

P(t) = population at time t

ii) Determine what year the population reached 7 billion

The year that population reaches 7 billion is 2013

solution attached below

iii) Determine if logistic growth or Gompertz growth was more accurate  considering world population reached 7 billion on October 31,2011

The logistic growth was more accurate because the when Logistic growth model was used, the year in which the population reached 7 billion was 2010 and this value is more closer to 7 billion on October 31 2011 ( given value )

Answers

Answer: d. a slower response to a stimulus and sustained without fatigue.

Explanation:

The activity of the enzyme ATPase is slower in the smooth muscles as compared to the skeletal muscles as a result the production of ATP is also slow this can directly affect the response giving ability of the smooth muscles to the stimulus so there is an delay in the response given by the smooth muscles. The smooth muscle cells are involuntary. They use very little amount of ATP does during energy requirements they sustain without fatigue.
