Which of the following could be a hypothesis for the function of the thick,
waxy coating on a pine needle?
A. If the thick, waxy coating is destroyed, the pine needle will turn
brown.
B. The thick, waxy coating prevents water loss.
C. What happens to the needle if the thick, waxy coating is
destroyed?
D. The tree would feel cold without the thick, waxy coating.
Answer:
B. The thick, waxy coating prevents water loss.
Explanation:
This is because the thick waxy coating needle refer to structure posses by plants or mostly xerophites plants to adapt to their environment. Plants that grow in area where there is no abundance of water for use normally posses these structures which will reduce evapotranspiration and conserve water. These plants normally have extensive roots to draw water.
A modification of a gene or chromosome that occurs during gamete formation or early development that permanently alters the expression of that gene for the lifetime of the individual is called:____.
a. epigenetic inheritance.
b. maternal effect.
c. sex-linked inheritance.
d. extra nuclear inheritance.
e. epistasis.
Answer:
Explanation:
Epigenetic inheritance is deals with the
study of the chemical modification of some genes or gene that are associated with proteins of an organism. An example of epigenetic is
Methylation it can either change rapidly during the life span of an organism or can be permanent if set early in the development of the embryo.
Epigenetic modifications are heritable, and can be passed from parents to offspring through genetic inheritance or passed down through multiple generations via transgenerational epigenetic inheritance.
In the beginning man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing.
a. True
b. False
Answer: True
Explanation:
The statement that "In the beginning, man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing" is true.
The creatures that were different from man became self supporting soon. If the present form had been the original form of man, he won't have survived.
Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan. He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis. Making edible, non-toxic food from petroleum is feasible. Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan. What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product. What shall we call it…”DinoSnack,” maybe? With interest in dinosaurs as high as it is, how can we go wrong?

dendritesAxon A cell body or soma9. The process where neurons communicate with one another at junctions is called synapse .
10. Explain the relation between the brain and the five senses.
Ans. The sense organs correspond to a defined region (or group of regions) within the brain where the nerve signals are received and interpreted. Your sense organs include your eyes, ears, nose, mouth, and skin, all have sensory receptors that are specific for certain stimuli. Sensory neurons send nerve impulses from sensory receptors to the central nervous system. The brain then interprets the nerve impulses to form a response.

Correct question:
In the Animals cladogram, which trait evolved two different times?Think and discuss: What could cause similar traits to evolve independently in different species?You will find the cladogram in the attached files.
Answer:
Bipedalism is the trait that evolved two different timesDifferent organisms in different spaces and times face the need to adapt to a similar environment. They manage to solve a problem from that particular ecological niche by developing the same traits, even when the involved groups are not closely related.Explanation:
Through the process of Convergent evolution, two phylogenetically independent organisms get to develop similar structures. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need for different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the given cladogram, the trait that evolved twice in evolution is bipedalism, reflecting the same need for chickens and humans to adapt to their environment in the same way and according to their habits.

3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.
5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
6. 1869
7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.
10. 20
11. A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).
12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.

Bats are natural reservoirs for Nipah virus and do not die from the infection. Knowing this information, would it be more valuable to report data for the incidence or prevalence of Nipah virus in bats (assuming that you also report the total number of bats in the population)?
Answer:
Prevalence would be more valuable
Explanation:
Prevalence is a measure of the frequency of individuals in a population affected by a condition during a particular period of time, while incidence is a measure that indicates the number of new individuals in a population who develop a condition during a particular period of time. Prevalence is different from incidence because prevalence includes all cases of a specified condition (i.e., new and preexisting cases). In consequence, in this case, prevalence is more valuable since it can be used to estimate the total number of infected bats. Conversely, incidence only is informative to determine the number of newly infected bats during a particular period of time, which may not be very informative because all infected bats (i.e., not only newly infected bats) can transmit the Nipah virus infection to humans.

What are two ways in which ultrasound technology produces images?
A. By the absorption of sound waves in the body
B. By detecting the frequencies of emitted sound waves
C. By using sound in frequencies that reflect off body tissues
D. By measuring the time it takes for reflected sound waves to be
detected
C and D
Hope this helps have a great day!!
The ultrasound images are produced by using the sound frequencies that reflect off body tissues and by measuring the time it takes for reflected sound waves to be detected. So the correct options are C and D.
What is ultrasound imaging?High-frequency sound waves are used in ultrasound imaging, also known as sonography, to look within the body.
Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as the activity of the body's interior organs.
Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation. A transducer (probe) is positioned either on the skin or within a bodily orifice during an ultrasonic examination.
To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed on the skin.
The ultrasound picture is created as a result of the waves' reflection off the body's structures. The information required to create a picture is provided by the intensity (amplitude) of the acoustic signals and the duration of the wave's passage through the body. Therefore the correct options are C and D.
