Why is air temperature above land warmer than the air temperature above water in the same location during the summer?

Answers

Answer:

Sea breezes happen during the hot, summer days due t the unequal heating rate of land and water

Explanation:

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

How does galaxy composition typically relate to the age of the stars in the galaxy? (1 point)

Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.

Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.

Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.

O Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.

H

Answers

Galaxy composition typically relate to the age of the stars in the galaxy

through Stars being able to form from dust and gas, so galaxies with

younger stars typically consist of higher proportions of dust and gas than

other galaxies.

Components of  a StarDustGas

The age of stars are usually determined through the amount of gas and dust

present in them. Stars burn gas to emit light and the younger ones have

more proportion of gas present than the older ones. The older ones have

less proportions due to more gas being burned over time.

The stated facts therefore makes option C the most appropriate.

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.

Answers

Answer:

prokaryotes

Explanation:

All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.

What is translation in prokaryotes?

In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.

This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.

Why can cells in the bone marrow produce both red and white cells

Answers

Answer:

1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.

Explanation:

2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.

3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on
approximately 8300 lane miles of Maine's state roads. They usually plan on an average of about 30 treatable events in a winter. This
includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a
storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout
the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative
effects on plant life and aquatic ecosystems. What is something your community can try to reduce the environmental impact of
salting? Select ALL that apply.
A)
Buy more snow plows and use less salt.
B)
Ban all salt based solutions in the state.
C)

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
