What best describes a high pressure system? Question 4 options: Warm, rising air that creates cloudy, rainy weather Warm, rising air that creates clear, sunny weather. Cool, sinking air that creates cloudy, rainy weather Cool, sinking air that creates clear, sunny weather

Answers

Answer:

a high pressure system : Cool, sinking air, that creates clear, sunny weather.

Explanation:

The characteristics of the high-pressure system is marked by the presence of the cold and sunny days as compared to those of the warm and low-pressure pressure regions of the world.  The air is light and lifts up easily and hence leading to the formation of clouds and rainfall. As compared to the cold air mass that is dense and hence has low moisture contents.

Una persona hala un trineo a lo largo de un espacio horizontal de 9 m la cuerda con que sa hala forma un ángulo de 60° con la horizontal y la fuerza para mover el trineo es de 125 N a. Calcular el trabajo realizado por la persona al halar el trineo

Answers

Answer:

978,75 Newton metro.

Explicación:

El trabajo realizado es de 978,75 Newton metro cuando la fuerza es de 125 newton, la distancia es de 9 metros y el ángulo es de 60 grados porque cuando usamos la fórmula del trabajo realizado obtenemos esta respuesta. La fórmula del trabajo es fuerza x desplazamiento x Sin (θ). θ muestra la dirección y el ángulo en el que se realiza la fuerza. Entonces, multiplicando todos estos valores obtenemos la respuesta para el trabajo realizado, que es 978,75 Newton metro.

Metals and minerals accumulate in specific regions on Earth due to _______ activity and as part of the rock cycle. When sustainable yield is achieved, the rate of replenishment is equal to the rate at which the resource is harvested. This means that the resource can be harvested _______. Plate motion can create the proper temperature and _______ underground for hydrocarbons to release from kerogen.

Answers

Answer: volcanic

indefinitely

pressure

Explanation:

It should be noted that metals and minerals are regarded as non renewable resources which implies that they cannot be replenished.

They accumulate as a result of volcanic activities which takes place in the Earth. The resources can be harvested indefinitely when there is achievement of the sustainable yield. Plate motion can then create the proper temperature and pressure underground that is required for the hydrocarbons to release from kerogen.

Answer:

1. Non-renewable

2. Volcanic

3. Indefinitely

4. Pressure

5. Metals are found in rocks and can be moved by erosion and rainfall. these processes carry metal away from weathered rock, causing metals to accumulate in sediments, rivers, and streams.

Explanation:

BrotherEye

The statement that can be used to describe DNA methylation is "A mechanism involving attachment of methyl groups to certain bases for the long-term inactivation of genes during development."

Option D.) is correct.

Define DNA methylation.

DNA methylation controls gene expression by attracting proteins implicated in gene repression or preventing transcription factor(s) from binding to DNA. The pattern of DNA methylation in the genome varies during development as a result of a dynamic process that includes both de novo DNA methylation and demethylation.

DNA methylation is an epigenetic mechanism that happens when a methyl group is added to DNA, altering the function of genes and influencing gene expression.

It's a process that involves attaching methyl groups to specific bases in order to inactivate genes for a lengthy time throughout development.

So, the statement that can be used to describe DNA methylation is option D.)

The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.

Answers

Answer:

A

Explanation:

The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.

Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.

An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.

The correct option is A.
