Answers
Answer:
Insertion
Explanation:
the strand Of DNA looks the same but it has an additional C after the 5th nucIeotide
In the given strand an insertion mutation is observed after the 5th nucleotide. Option C is correct.
As with genomics, an insertion is a mutation that adds one or more DNA nucleotides to a DNA segment. Insertions can be as small as one nucleotide or as large as an entire chromosome.
An insert alters the DNA sequence by inserting one or more amino acids into the gene. The resulting protein produced from the gene may be defective. A deletion alters the DNA sequence at least by removing one amino acid from a gene.
In a small-scale insertion mutation, one or more nucleotides are inserted into the sequence. In a large-scale insertion, a region of the chromosome is translocated.

pongids: a. are incapable of walking bipedally b. can walk bipedally only by holding on to branches with their arms c. are capable of bipedal locomotion, but inefficiently d. are, in fact, habitually bipedal
Answers
One of the earliest adaptations made by hominids was bipedalism, and there are several theories as to how the human ancestors acquired it. One of them claims that after a group of our ancestors started living in Savannah habitats, bipedalism emerged (open areas covered with grasses). The Savannah lineages didn't have many trees to climb, so the upright posture let them see predators in the distance. Other lineages remained in the forests, where they could use the treetops and branches for protection and to collect food.
The second theory links the use of tools to the evolution of human bipedalism. The two forelimbs are free to explore the environment, aid in the use of tools, and even gather food while moving because a species does not move on all four limbs.
With this knowledge, we can conclude that bipedalism gave the human race a free arm to build technology and allowed them to move more slowly while walking, among other benefits.

It binds with dopamine receptors to produce the pleasurable effects associated with smoking. quizlet
Answers
Nicotine is a highly addictive substance that can have serious health consequences, and it binds with dopamine receptors to produce the pleasurable effects associated with smoking.
The statement "It binds with dopamine receptors to produce the pleasurable effects associated with smoking" refers to nicotine.
Nicotine is a naturally occurring alkaloid found in the nightshade family of plants.
It is a highly addictive substance that is found in tobacco products such as cigarettes, cigars, and chewing tobacco.
When nicotine is smoked or ingested, it binds with nicotine receptors in the brain, which then triggers the release of dopamine.
Dopamine is a neurotransmitter that is responsible for pleasure and reward.
This is why smoking can be so addictive, as the dopamine release creates a pleasurable sensation that the brain craves.
The more a person smokes, the more they become desensitized to the dopamine release.
This can lead to an increase in smoking to achieve the same level of pleasure, which can ultimately lead to addiction.
Smoking can have numerous negative health effects, including increased risk of lung cancer, heart disease, and stroke. It is important to quit smoking in order to improve overall health and reduce the risk of these health problems.
Overall, nicotine is a highly addictive substance that can have serious health consequences, and it binds with dopamine receptors to produce the pleasurable effects associated with smoking.

Consider these versions of The War of the Worlds. Excerpt 1, from H. G. Wells's novel The War of the Worlds: The common round the sand pits was dotted with people, standing like myself in a half-fascinated terror, staring at these creatures, or rather at the heaped gravel at the edge of the pit in which they lay. And then, with a renewed horror, I saw a round, black object bobbing up and down on the edge of the pit. It was the head of the shopman who had fallen in, but showing as a little black object against the hot western sun. Now he got his shoulder and knee up, and again he seemed to slip back until only his head was visible. Suddenly he vanished, and I could have fancied a faint shriek had reached me. Excerpt 2, from Howard E. Koch's script for Orson Welles's radio adaptation: PHILLIPS: Ladies and gentlemen, you've just heard Mr. Wilmuth, owner of the farm where this thing has fallen. I wish I could convey the atmosphere . . . the background of this . . . fantastic scene. Hundreds of cars are parked in a field in back of us. Police are trying to rope off the roadway leading to the farm. But it's no use. They're breaking right through. Cars' headlights throw an enormous spot on the pit where the object's half buried. Some of the more daring souls are now venturing near the edge. Their silhouettes stand out against the metal sheen.

using your understanding of genetic variation and evolutionary processes, why does the african human population have more genetic diversity than european or asian populations? choose all that apply.
Answers
African populations exhibit significant levels of genetic diversity and phenotypic variation since modern humans are thought to have originated there and have adapted to a variety of environments.
The variety of various inherited features within a species is referred to as genetic diversity. There would be many people with a wide range of diverse traits in a species with significant genetic diversity. For a population to adapt to changing surroundings, genetic variety is essential. The ability of a population to adjust to changes will be lowered if a highly chosen and low diversity strain—such as fish populations raised for aquaculture—is transplanted into a wild population. One of the best examples of genetic variety is the various breeds of dogs that have been created by selective breeding. There are more than 50,000 different types of rice.

some steroid hormones do not require membrane receptor because they:
a. are small enough to pass directly though pores in the membrane.
b. are lipid-soluble and pass though the bilayer.
c. pass through special channels
d. are water-soluble.
e. dissolve in the cholesterol of the membranes
Answers
some steroid hormones do not require membrane receptor because they are lipid-soluble and pass through the bilayer . Option b is correct answer.
Steroid hormones are a class of hormones that are derived from cholesterol and are characterized by their lipid-solubility. Being lipid-soluble allows these hormones to easily pass through the plasma membrane, which is composed of a lipid bilayer. Unlike water-soluble hormones, which rely on membrane receptors to initiate cellular responses, lipid-soluble hormones can diffuse across the plasma membrane and bind directly to intracellular receptors located in the cytoplasm or nucleus.
Once inside the cell, the hormone-receptor complex acts as a transcription factor, influencing gene expression and leading to various cellular responses. Because steroid hormones can freely cross the plasma membrane, they do not require membrane receptors lipid-soluble or specialized channels for their entry into the cell. This direct access to the intracellular receptors allows for a rapid and direct response to hormone signaling.
It is important to note that not all hormones can pass through the plasma membrane directly. Water-soluble hormones, for example, require membrane receptors on the cell surface to initiate signal transduction pathways.

a ciliate. Ciliates are a type of single-celled organism belonging to the Ciliophora.
They are characterized by the presence of numerous hair-like structures called cilia, which are used for locomotion and feeding. Cilia are short, hair-like projections that cover the entire outer surface of the cell membrane.
These cilia beat in a coordinated fashion, creating a wave-like motion that allows the ciliate to move through the water.
Ciliates exhibit a wide range of shapes and sizes, but they are typically oval or elongated in form.
They have a well-defined nucleus and often possess other specialized structures such as contractile vacuoles for osmoregulation and oral grooves for feeding.
Ciliates are also known for their ability to undergo complex cell division processes, including conjugation, which involves the exchange of genetic material between two individuals.
Observing a single-celled organism with moving cilia under the microscope is a common sight in freshwater environments such as ponds, lakes, and streams, where ciliates are abundant.
