12. What biological organisms are in topsoil?
decaying and living plant and animal life
fossil remains from millions of years ago
nutrients from basic building material
Kard soil, clay, and large rocks

Answers

Answer 1

Answer:

Many of the millions of organisms that live in the soil, including bacteria, fungi, insects, and earthworms, are known as decomposers. They live on the remains of dead plants and animals and break down these organic remains into simple chemicals that are released into the soil.

The human brain communicates with the rest of the body through networks of what?

Answers

Through nerves attached to the brain and to the spinal cord. When an action potential traveling down the axon reaches a terminal button, they secrete a chemical called a neurotransmitter.

The brain communicates with the rest of the body through the spinal cord, which runs from the base of the brain all the way down the back. The spinal cord is made up of lots of nerves, and these nerves branch out into more nerves that travel to every part of the body.

Peter is pushing the rock but the rock is not moving. Choose the statement that describes the force(s) being applied in the image.

a boy pushing a rock, but the rock is not moving

The force of the push is an unbalanced force.
The forces acting on the rock are balanced.
A weaker force of pushing would result in unbalanced forces.
The force of gravity is pulling the rock upwards.

Answers

The answer is that the forces acting on the rock are balanced.

Explanation: Basically since the object is not moving we can consider this system to have a net force of zero (where are forces are balanced). In this problem, the force applied equals the static friction pushing back, and the force of gravity equals the normal force exerted by the ground on the rock.

Estimating the weight of a dinosaur using only bones is difficult. Another way is by using scale models. The density of a dinosaur is scaled based on the average density of what living animal

Answers

Given what we know about the methods used by scientists to estimate the weight of a dinosaur, we can confirm that the density of a dinosaur is scaled based on the average density of the common crocodile.

Scaling the density of an extinct animal based solely on bones can be a daunting task. Since the bones themselves do not offer much information on which to base such a calculation, scientists are often forced to rely on other estimations. One such example is the bone scaling method.

This method relies on the genetic relationships shared between the dinosaur and current-day living animals. This offers the ability to compare the dinosaur to the known body mass of a modern-day living animal. The animal most commonly used is the crocodile, however, though this method can provide the scientists with a degree of accuracy, it lacks precision.

Which are examples of active transport?
Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis

Answers

Answer:

Exocytosis, phagocytosis, and pinocytosis

Explanation:

Active transport is when energy is used to move substances across the cellular membrane.

Exocytosis requires energy to remove materials from the cell; it is active.

Phagocytosis also requires energy; it is active.

Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.

Pinocytosis is a form of endocytosis and requires energy; it is active.

Explain how water move from cell to cell in a leaf

Answers

Answer:

By osmosis, water enters the root and travels through the root cells until it reaches the xylem vessels. These canals carry water from the stem to the leaf. Transpiration is the process of removing water from the leaves of plants via evaporation.

Explanation:

Water moves from cell to cell in a leaf through a process called transpiration, facilitated by a combination of cohesion, adhesion, and capillary action in the plant's vascular system.

Transpiration: Transpiration is the process by which water vapor exits the leaf's stomata (tiny openings on the leaf surface) into the surrounding atmosphere. As water vapor evaporates from the cells within the leaf, it creates a lower pressure within the leaf's interior, drawing water molecules from neighboring cells.

Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, is the attraction between water molecules and the surfaces of other materials, such as the walls of plant cells and the walls of xylem vessels. These properties work together to create a continuous column of water within the plant's vascular system, allowing water to move upward from the roots to the leaves.

Give two ways that differentiation is the same in plants and animal.​

Answers

Cell elongation does not occur in animals. The cells of multicellular animals and plants must also differentiate , so that its cells develop features that enable them to fulfil specific roles. Cells that have differentiated have become specialised.

Differentiation in plants and animals involves the specialization of cells for specific functions, and it results in the development of different tissues and organs.

What is differentiation in plants and animals?

Differentiation refers to the process by which cells become specialized in structure and function. In plants and animals, this process occurs during development and results in the formation of different types of cells, tissues, and organs.

During differentiation, cells undergo changes in gene expression, which leads to the production of different types of proteins and other molecules. These changes can be triggered by various signals, such as hormones, growth factors, and environmental cues.

In animals, differentiation occurs during embryonic development and results in the formation of different types of tissues, such as muscle, bone, and nerve tissue. In plants, differentiation occurs during both embryonic development and growth and results in the formation of different types of tissues, such as root tissue, leaf tissue, and stem tissue.

Answer:

Explanation:

"All compounds are substances,  but not all substances are compounds."

In simpler terms, let us use an example. Look at the image below.

In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.

If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.

The student that provides the best explanation is as follows:

Student 3: Chloroplasts produce simple sugars which mitochondria use to provide energy for the cell.

What is Cellular Homeostasis?

Cellular homeostasis may be defined as the capability of a cell in order to maintain relative stability and function as alterations take place in the internal or external environment.

According to the question, the Lysosomes are the fatal or self destrcutive bags for living cells. Vacuoles store nutrients as well as waste substances of the whole cell in order to prevent cells from being contaminated.

The sorting of important molecules like lipids and proteins is initiated through the endoplasmic reticulum and proceeds to the Golgi bodies through the anterograde pathway.

While the photosynthetic organelle chloroplast captures the radiation energy from the sun and synthesizes simple sugar like glucose which is used by another organelle mitochondria to provide energy for the cell.
