only a small portion of the organisms that lived in the geologic past have been preserved as fossils. which condition best increases the chance that an organism will become fossilized? responses slow burial and hard body parts slow burial and hard body parts slow burial and large body size slow burial and large body size rapid burial and large body size rapid burial and large body size rapid burial and hard body parts
Answers
The condition that best increases the chance that an organism will become fossilized in the geologic past is "rapid burial and hard body parts."
The condition that best increases the chance that an organism will become fossilized is slow burial and hard body parts. This is because slow burial allows for the organism to be buried in sediment before it decays or is scavenged, and hard body parts like bones, shells, or teeth are more likely to survive the fossilization process than soft tissue.
The condition that best increases the chance that an organism will become fossilized in the geologic past is "rapid burial and hard body parts." This is because rapid burial helps protect the organism from decomposition and scavengers, while hard body parts are more likely to be preserved as fossils due to their durability.

which type of channels are found in axons of all types of neurons that open in response to change in membrane potential?
Answers
The relative concentrations of different ions inside and outside the cell are regulated by voltage-gated ion channels.
The membrane potential is the total charge differential between the cell's inside and exterior. Changes in the membrane voltage cause voltage-gated ion channels to open.
Charged molecules or ions cannot pass through the lipid bilayer membrane that encloses a neuron. Ions must traverse unique proteins known as ion channels that span the membrane in order to enter or exit the neuron. Ion channels can be inactive, closed, or any combination of these states, as seen in In order for some ion channels to open and let ions enter or exit the cell, they must first be activated. These ion channels can alter their form in response to environmental changes. Voltage-gated ion channels are ion channels that alter their shape in response to voltage changes.

If pyruvate processing is blocked, what will happen to the levels of oxaloacetate and citrate in the citric acid cycle?.
Answers
There will be an increase in oxaloacetate and a decrease in citrate.
What happens if a cell doesn't have enough oxaloacetate?Since pyruvate cannot produce oxaloacetate, it is diverted to alternative pathways instead, which result in the production of lactic acid and alanine. Oxaloacetate is necessary for the urea cycle and gluconeogenesis to occur.
The citric acid cycle's importance of oxaloacetate is explained.Response and Justification: One of the crucial intermediates of the Krebs cycle is oxaloacetate. It reacts with acetyl-CoA to produce citrate as a byproduct.
When the citric acid cycle is complete, what happens to the malate or oxaloacetate?Malate is dehydrogenated to create the new oxaloacetate required for the cycle's final reaction, which allows acetyl coA to enter.

what is the most likely order of the linked genes r, s, and t if the distance between t and s is 22 m.u., the distance between s and r is 8 m.u., and the distance between r and t is 14 m.u.?
Answers
Based on the given information, the most likely order of the linked genes r, s, and t would be r - s - t.
Based on the given distances between the linked genes r, s, and t, we can determine the most likely order by analyzing the map units (m.u.) between them.
The distance between t and s is 22 m.u., which suggests that t and s are farther apart from each other compared to the other gene pairs. Similarly, the distance between r and t is 14 m.u., indicating that r and t are closer together compared to t and s.
Using this information, we can deduce that the order is most likely r - t - s.
The distance between s and r is 8 m.u., which is smaller than the distance between r and t. This implies that s and r are closer together than r and t. Therefore, the most probable order of the genes is r - t - s.
It's important to note that genetic mapping is subject to variations and uncertainties, and the actual gene order can sometimes deviate due to factors like genetic recombination. However, based on the given distances, r - t - s appears to be the most likely order.

Answers
The following lists the layers of the integument in the order from most superficial first to deep is A. epidermis, papillary dermal layer, reticular dermal layer.
The integument is the largest organ of the body, and it is also known as the skin. The skin is divided into three distinct layers: the epidermis, dermis, and hypodermis. The integument functions as a protective barrier and performs a variety of physiological functions. It also acts as an organ of sensation and plays a role in maintaining homeostasis.
The epidermis is the outermost layer of the skin, and it is composed of keratinocytes, which are cells that produce a tough, protective protein called keratin. The dermis is located beneath the epidermis and is made up of connective tissue. It contains blood vessels, lymph vessels, nerve fibers, hair follicles, and sweat glands. The hypodermis is the deepest layer of the skin and is composed of adipose tissue. It is the layer that lies beneath the dermis and attaches the skin to the underlying muscle and bone tissue.

Read each of these scenarios describing the evolution of decreased body hair in humans. Scenario X: As hominins migrated to more open environments and became mid-day hunters/scavengers, they were exposed to higher levels of heat. In order to effectively cool the body, hominins needed to have less hair, so a mutation for decreased body hair occurred. Eventually, evolution favored those with less body hair such that all hominins had less body hair. Scenario Y: As hominins migrated to more open environments and became mid-day hunters/scavengers, they were exposed to higher levels of heat. Hominins with less dense hair, a trait that had heritable variation within the population, maintained a cooler body temperature and were more successful in obtaining food. Over time, hominin populations evolved to have less body hair. Scenario ____ describes evolution by natural selection. I know this because_______. Group of answer choices X; mutation occurs that increases survival of the species X; it describes evolution of individuals who became adapted to the environment. Y; it involves heritable variation and fitness Y; hominins acquired a needed characteristic so that they were more successful hunters
Answers
Scenario Y describes evolution by natural selection. I know this because (C) it involves heritable variation and fitness. In this scenario, as hominins migrated to more open environments and faced increased heat exposure, those with less dense hair had a heritable variation within the population.
This trait allowed them to maintain a cooler body temperature, giving them a fitness advantage in obtaining food as mid-day hunters/scavengers. Over time, the hominin populations evolved to have less body hair as natural selection favored individuals with this advantageous trait.
This process of natural selection involves the differential survival and reproduction of individuals based on their inherited traits that enhance their ability to adapt and thrive in their environment.
The scenario exemplifies the key components of natural selection, including heritable variation, fitness differences, and the resulting adaptation to the environment. As a result, Scenario Y best describes evolution by natural selection in the context of decreased body hair in hominins.

What evidence would NOT suggest that the fluid in the nucleus is different from the cytoplasm?
Answers
There are a few pieces of evidence that would not suggest that the fluid in the nucleus is different from the cytoplasm. Firstly, if both the nucleus and the cytoplasm have similar concentrations of ions, proteins, and other molecules, this would indicate that the fluid in both compartments is likely to be similar.
Secondly, if there is no visible difference in the color or texture of the fluid in the nucleus compared to the cytoplasm, this may also suggest that they are similar. Lastly, if the same molecules or compounds are able to freely diffuse between the nucleus and the cytoplasm, this would also suggest that the fluid in both compartments is similar.
It is important to note, however, that just because these pieces of evidence do not suggest a difference in the fluid between the nucleus and the cytoplasm, it does not necessarily mean that there is no difference. Additional research using more sensitive techniques may be needed to confirm or refute any potential differences.
