How can you use isobars to determine approximate wind speed and direction using the pressure map?
Answer:
Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.

Number of Differences Pair of Species 2 Porpoise and S. Whale 3 Deer and Giraffe 3 Porpoise and Rt. Whale 3 Hippo and Porpoise 3 Hippo and S. Whale 3 Cow and Giraffe 3 S. Whale and Rt. Whale 4 Hippo and Rt. Whale 4 Deer and Cow Please answer the following questions in complete sentences. 2. Which 4 species are found in all possible combinations with each other
Answer:
The correct answer is - Porpoise, Sperm, Whale, Rt. Whale, and Hippo.
Explanation:
In the question the following combinations are given of the various species with only 2-4 differences in their DNA:
2 Porpoise - Sperm Whale
3 Sperm Whale - Rt. Whale
3 Porpoise - Rt. Whale
3 Hippo - Sperm Whale
3 Hippo - Porpoise
3 Cow - Giraffe
3 Deer - Giraffe
4 Hippo - Rt. Whale
4 Deer - Cow
Here numbers represent the differences in their DNA and on the basis of this combination we can say that Porpoise, Sperm, Whale, Rt. Whale, and Hippo found in all possible combinations with one another. It also tells that all these species diverged from the common ancestor.
How could you decrease the amount of energy an object has?
The amount of energy that an object has can be decreased by decreasing its temperature.
Let us recall that the temperature of a body is a measure of the average kinetic energy of the molecules of the body. The molecules in a body are always in constant random motion.
The kinetic energy possessed by the body is dependent on its temperature. To control the amount of energy that an object has, we either increase or decrease its temperature.
If we want the amount of energy that an object has to decrease, we simply decrease its temperature.

Match the types of roots to their properties. a root that is conical in shape and develops from the radicle a root that develops like a tuft of hair like roots and is short-lived a root that grows from plant parts other than roots a root that grows from branches to the ground a root that grow out of the soil adventitious root arrowRight pneumatophores arrowRight tap root arrowRight fibrous root arrowRight prop root arrowRight
Answer:
adventitious root ➡ a root that grows from plant parts other than roots
pneumatophores ➡ a root that grow out of the soil
tap root ➡ a root that is conical in shape and develops from the radicle.
fibrous root ➡ a root that develops like a tuft of hair like roots and is short-lived.
prop root ➡ a root that grows from branches to the ground
Explanation:
Adventitious roots are known to be roots that grow from a tree organ other than the root. The growth can be from the stem or leaf of that tree. This root makes it possible for vegetative propagation of plants to take place through stem or leaf cuttings. It can seen on rhizomes, corms, and tubers.
Pneumatophores are roots that grow out of the soil. They grow in saline mud and grow upward out of the mud and water. These type of root system are found in mangrove species. A tap root system is formed when the radical keeps growing and some other roots form along the tap root. They are conical in shape too.
How does binding of complement-opsonized microbes to CR1 facilitate clearing of the microbe from the host? a. Secretion of proinflammatory cytokines b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes. c. Promotion of phagocytosis of opsonized microbes by leukocytes d. None of the answers occur. e. Mediating phagocytosis of C3b-opsonized pathogen by B cells
Answer:
The correct answer is - b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes.
Explanation:
Binding of complement - opsonized to CR1 makes the microbe palatable to the phagocyte for the phagocytosis and removes the microbe from the host cell. The mechanism of the removal takes place by the promotion of phagocytosis by the leukocytes.
Secretion of the pro-inflammatory cytokines also takes place in the clearing of the microbe and the phagocytosis is mediated by the B cells of the C3b-opsonized pathogen.
In a certain breed of cats, having black hair is the result of two dominant alleles for hair color (HH). The heterozygous genotype (Hh) produces a cat that has black and white spots.

Explanation:
During most of the cell's life, the chromosomes will be in the form of
O Chromatin
O Sister chromatids
O Homologous chromosomes
O Tetrads
During most of the cell's life, the chromosomes will be in the form of - Chromatin.
The DNA wrapped around histones is further organized into higher-order structures that give a chromosome its shape.
This form of the chromosome is called chromatin and it is the form chromosome most of the life of the cell.In this form chromatin is decondensed, meaning that it exists in long, thin strings form.It is found in the interphase most of the cell's life.Thus, During most of the cell's life, the chromosomes will be in the form of - Chromatin.

There are three alleles for the ABO blood group in humans. Why are there only two alleles normally present in any individual?
1. The alleles for the ABO blood group always segregate independently during meiosis.
2. Each parent contributes only one allele for the ABO blood group to the offspring
3. Every gene for the ABO blood group must be recessive.
4. The alleles that determine the ABO blood group are on the X-chromosome.
Answer:
2. Each parent contributes only one allele for the ABO blood group to the offspring
Explanation:
Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.
Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.

Which of the following is a peptide bond?
A.C-H bond
B.N-H bond
C.C-C bond
D.C-N bond
Answer:
The correct answer is - D.C-N bond
Explanation:
A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.
So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.
So the peptide bond that formed by this reaction is involve bonding of C-N bond.

Can you please help me I am super stuck
Answer:
a.) 12 Newtons
b.) Same Direction
c.) Unbalanced
Explanation:
The system shows 2 individual forces:
A force of 5 N pulling the box LEFT
A force of 7N pushing the box LEFT
Both forces are LEFT, so they have the same direction.
Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:
Resultant force's magnitude is then: 5N + 7N = 12N
Resultant force's direction: unchanged = LEFT
Since the resultant force's magnitude is not 0, the system is unbalanced.

Place the Polymerase Chain Reaction events listed below in the order in which they occur. - Double-stranded DNA is produced - DNA sample is heated - Test tube with DNA sample is placed in machine - Taq polymerase initiates DNA synthesis - DNA denatures
Answer:
1- Test tube with DNA sample is placed in machine
2- DNA sample is heated
3- DNA denatures
4- Taq polymerase initiates DNA synthesis
5- Double-stranded DNA is produced
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).
