Which of the following is TRUE about the fossil record? Group of answer choices It is sadly incomplete and lacking in all transitional forms. It gives useful information about environments and the ways past organisms lived. Only animals with hard skeletons are preserved. It is best in deep forests where dead organisms have not been disturbed.
Answer:
It gives useful information about environments and the ways past organisms lived
Explanation:
A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.
From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.
Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification portion below, the definition of the topic is mentioned.
Explanation:
This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic. These are assumed that understand the connection to a specific community follow these rituals only to solve difficulties they have previously faced due to errors perpetrated by certain ancestors.What makes bottleneck dolphins such “ingenious fishermen”?

Answer:
The correct answer is -
wetlands - land and water
estuaries - freshwater and salt water
Explanation:
There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.

A metal rod would not be a good choice for roasting marshmallows because
metal transfers thermal energy.
Answer:
O As the air around the campfire is heated and becomes less dense, it rises and moves upward.
Explanation:
This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.
Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.
What is convection of heat?Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.
The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.
Therefore, the correct option is C.

Explain how wildfires help restore soil nutrients to forest ecosystems.
Answer:
Wildfire help restore soil nutrients - Wildfire kills off the soil organisms that consume soil nutrients. Wildfires restore soil nutrients by decreasing the amount of underbrush in forests that contribute to nutrient loss. Wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.
Explanation:
Wildfire help restore soil nutrients by eliminating soil organisms that consume soil nutrients and decomposition of materials that help to renew soil nutrients.

Which correctly lists the three main ocean zones?
O deep, neritic, surface
O intertidal, deep, surface
O neritic, intertidal, open ocean
O open ocean, deep, continental
Answer:
Honestly I think it's C
Explanation:
The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.
What are the three main zones?The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.
The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.
Apart from the three main ocean zones, there other oceanic zones are epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.
Therefore, the three main ocean zones are neritic, bathyal, and abyssal.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins
Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.
