What type of weather is associated with High Pressure systems?

Question 4 options:

it is always different


snowy weather


clear sunny skies


cloudy stormy weather

Answers

Answer:

it's option C) clear sunny skies.

The type of weather associated with High pressure systems is : ( C ) clear sunny skies

High pressure systems have a greater amount of air pressure within their systems, when compared to its surroundings. Due to the presence of high air pressure within the system the air in the system is pushed into the surroundings.

Types of pressure systems

There are two types of pressures systems and they are

High pressure system ; Possess more air pressure within the system Low pressure system ; Possess less air pressure within the system

As the air leaves the high pressure system into the surroundings the system becomes clearer ( i.e clear sunny skies is evident in a high pressure system).

Hence we can conclude that the type of weather associated with high pressure systems is clear sunny skies

Cell membranes are made up of a bilayer of phospholipids that are very selective about what substances can pass through.The table below shows the different types of molecules that can enter a cell. It compares the concentration on the outside to the inside of the cell, its relative size, and whether it is polar, nonpolar, or an ion. Determine how each molecule can pass into the cell. Is it by passive transport, active transport, or endocytosis? (3 points)​

Answers

Answer:

Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis

Explanation:

js trynna get points lol

The molecules can pass into the cell by passive transport, active transport, or endocytosis.

Molecule | Concentration Outside | Concentration Inside | Size | Polarity | Transport | Mechanism

Glucose High Low Small Polar Diffusion

Oxygen High Low Small Nonpolar Diffusion

Sodium High Low Small Ion Active transport

Chloride Low High Small Ion Active transport

Amino acids Low High Medium Polar Carrier-mediated transport

Large protein Low High Large Polar Endocytosis

Glucose and oxygen can pass into the cell by diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Glucose and oxygen are both small molecules, and they are both polar. This means that they can dissolve in the phospholipid bilayer of the cell membrane.

Sodium and chloride can pass into the cell by active transport. Active transport is the movement of molecules from an area of low concentration to an area of high concentration. Sodium and chloride are both ions, which means that they are charged particles. This means that they cannot dissolve in the phospholipid bilayer of the cell membrane. Instead, they need to be transported across the membrane by special proteins called ion pumps.

Amino acids can pass into the cell by carrier-mediated transport. Carrier-mediated transport is a type of passive transport that uses carrier proteins to transport molecules across the cell membrane. Amino acids are polar molecules, but they are larger than glucose and oxygen. This means that they cannot simply diffuse across the cell membrane. Instead, they need to be transported across the membrane by carrier proteins.

Large protein can pass into the cell by endocytosis. Endocytosis is a process by which the cell engulfs large molecules or particles. The cell membrane forms a pocket around the molecule or particle, and then the pocket pinches off to form an endocytic vesicle. The endocytic vesicle then fuses with a lysosome, where the molecule or particle is broken down.

What is geology?

Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.

In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.

According to the previous process, it can be inferred that the missing layers in each column are:

which of the following hormones produced in the anterior pituitary stimulates the production of progesterone and estrogen by ovaries and is needed for ovulation?

Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.

Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs.

what are the role of Luteinizing hormone ?

These hormone are released from ductless Endocrine cells which release their secretion i.e., hormones directly into blood.

The  FSH (follicle stimulating hormone) is secreted by pituitary gland  which helps in controlling menstrual cycle and stimulation of ovaries for egg production.

The hormone LH (Luteinizing hormone) is secreted from pituitary gland,  helps in physical development and maintaining pregnancy.

Thus, both FSH and LH are produces by pituitary gland and their functions are to control menstrual cycle and maintaining pregnancy respectively.

Help please and are the ones that already answered to are correct ?

Answers

Yes, all of your answers are correct except for number 12. Instead I would say a food chain outlines who eats whom but a food web is all of the food chains in an ecosystem.

Primary consumers are basically herbivores, such as squirrels, rabbits, crickets, etc.

Secondary consumers are carnivores/omnivores, animals that eat other animals such as foxes, snakes, and owls.

Higher order consumers are animals that can eat more things, like humans for example, because we eat animals that are bigger than us like cows but we also eat plants.

Omnivores are animals that eat meat and plants, such as humans and mice because according to your food web, mice also eat meat.

I can’t see the picture very well because it’s blurry, but i think the owl eats some kind of animal that looks like a frog and snakes, so if the owl is removed the frog animal thing and snakes would increase.

Take Lummi Island, for example, the smallest of the San Juan Islands in northwest Washington and still a well-kept secret. Though its meager population quadruples to 4,000 with the summer tourist season, it never feels the slightest bit crowded. One can always find a deserted beach to roam or a forest path to explore. The mainland is only a 12-minute ferry ride away, so city life is within reach. Bainbridge Island, near Seattle, is another prime choice for those wishing to live somewhere with peace and quiet but proximity to a city. Many Seattle employees live on the island and commute each day to their downtown jobs. Vashon Island, near Tacoma, might seem too small for some. There is no "town" to speak of, but a quiet little artists' community thrives there. Family homes on the islands mentioned above are no more expensive than on the mainland. Such houses offer stellar views of surrounding landscape, including mountains, waterways, and other scenic islands. Otter, bald eagles, seals, and even whales are frequent visitors to Pacific coastal islands. They are a nature lover's paradise and also offer perfect settings for stargazers and photographers. Quite a few island inhabitants were once tourists who found they couldn't bear to leave and made the island their home. If there are drawbacks, they are only these: there is usually a minimum of culture in terms of theater or music events. But all that means is an excursion into town now and then to get your fix. The same is true if you want a wide variety of food or like to eat in restaurants. The only other minor drawback is the ferry schedule, which can be sporadic. There are also periods of time each year when ferries are in "dry dock" and not running due to planned or unplanned repairs. Still, for those wanting to escape the noise and stress of city life, islands are a perfect choice. They are among the nation's few remaining unspoiled places to call home.Which sentence best summarizes the author's attitude in this selection? A.
