9. What type of bond is pictured in the image below?

a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond

ONLY 9

Answers

Answer:

c. metallic bond

Explanation:

Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.

The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Patients generally report conscious awareness of posthypnotic suggestions. Please select the best answer from the choices provided T F

Answers

Answer:

false

Explanation:

edge 2020

Conscious awareness of posthypnotic suggestions is a false statement because it creates a subconscious.

What are posthypnotic suggestions?

The directive was given to the subject during a hypnotic trance that must be carried out once the subject awakens.

A post-hypnotic suggestion is essentially a specific directive to be followed after the hypnotherapy session to the subconscious.

An illustration of this would be going to a hypnotist for help with weight reduction and having the suggestion made that every time you feel like a sweet sort of meal, you will feel like drinking some water instead" ingrained in your subconscious.

Therefore posthypnotic suggestions of having conscious awareness are false statements.

In leopards, being shy (S) is dominant to being sassy (s), and being timely (T) is dominant to being tardy (t).
A female leopard that is
heterozygous for both the S and I trait mates with a male leopard that is also
heterozygous for both traits. Both the S and I traits assort independently from one another.
What is the probability that they will have an offspring that is sassy and timely?

Answers

The probability that the leopards will have an offspring that is sassy and timely is 3/16

This question involves two different genes. The allele for being shy (S) is dominant to the allele for being sassy (s) in the first gene while the allele for being timely (T) is dominant to being tardy (t).

According to this question, A female leopard that is heterozygous for both the S and T traits i.e. SsTt mates with a male leopard that is also heterozygous for both traits i.e. SsTt

The two heterozygous leopards (SsTt) will produce the following gametes: ST, St, sT, and st

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

S_T_ = shy, timely (9)S_tt = shy, tardy (3)ssT_ = sassy, timely (3)sstt = sassy, tardy (1)

According to this question, the probability that the two leopards will have an offspring that is sassy and timely is 3/16.

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?

Answers

Answer:

Mutualism

Explanation:

Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.

In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.

Why is meiosis important in maintaining genetic diversity?

Question 6 options:

A Meiosis creates diversity by cutting each chromosome exactly in half.


B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.


C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.


D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.

Answers

Answer:

We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Explanation:

Brainliest please?

Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.    

Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.

The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.

Other options-

A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.

C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.

D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.

Answers

Answer:

Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X

objective by raising the oil objective a little to avoid the damage to objective lens. Critique his

technique. (1 pt.)

Answers

Answer:

See the answer below

Explanation:

In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.

For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

What happens to the total blood flow during heavy exercise compared to at rest?

Answers

Blood flow is greater when you exercise because the blood vessels in your muscles dilate. Imagine water flowing through a fire hose compared to a garden hose. Adenosine triphosphate, or ATP, is the way your body uses biochemicals to store and use energy. When ATP gets used up in working muscles, the muscles themselves produce metabolic byproducts (for example, adenosine, hydrogen ions and carbon dioxide). As these byproducts leave the muscle cells, they cause small, thin-walled blood vessels (capillaries) within the muscle to expand or dilate, which is called vasodilation. The dilated capillaries allow increased blood flow, which delivers more oxygenated blood to the working muscle.
