Answer:
17 m/s
Explanation:
s=d/t
s=34m/2s
Answer:
34/2 = 17 m/s

A wetland that contains a mixture of fresh water and salt water is called
an estuary
a stream
a river.
a pond
Answer:
an estuary
Explanation:
A wetland which contains a mixture of fresh water and salt water is called as an estuary. Thus, the correct option is A.
What is an estuary?An estuary is an example of a partially enclosed, coastal water body where the freshwater from rivers and streams mixes up with the salt water from the ocean bodies. Estuaries, and their surrounding lands, are the places of transition from the land area to the sea area.
Estuaries and their surrounding wetlands are the bodies of water which are usually found where the rivers meet the sea. Estuaries are the home to many of the unique plant and animal communities which have adapted to the brackish water, which is a mixture of fresh water draining from the land and the salty seawater.
Therefore, the correct option is A.

Explain why Hurricane Harvey traveled from the east (Africa) towards the west (Florida) when our weather in Wisconsin starts in the west and travels east?
PLEASE HELP!
Answer:
Due presence of Sahara desert that is responsible for the formation of this hurricane and its movement towards Florida.
Explanation:
Hurricane Harvey traveled from the Africa towards the Florida because these hurricane formed at the African region due to the presence of Sahara desert. The hot and dry wind of Sahara desert meets with the cool, moist air from the south produces these hurricane which then moves from the Africa to the west side where Florida is located so that's why Hurricane Harvey traveled from Africa towards the Florida.

Which product of respiration is considered waste material and leaves the alveoli?
O oxygen
O water
O carbon dioxide
O carbon monoxide
Answer:
In our respiratory system, carbon dioxide is the waste material that we expel when we breathe out. The answer is C, Carbon Dioxide
I hope you have a great day!
The waste product of respiration is
C. Carbon dioxide
The oxygen consumed via stomata is used up by cells.
Respiration in leaves:Oxygen from the air enters a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata. The oxygen used by cells in the leaves to disintegrate glucose into water and carbon dioxide.
Thus, option C is correct.

. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
The product that will be present in the test tube will be amino acids.
Protease is an enzyme that acts on protein by converting it into different
types of amino acids.
Amino acids are referred to as the building block of life and are important
nutrients in growth and replacement of worn-out tissues. The protease acts
on the protein by breaking the peptide bonds under the required
temperature.
An inadequate temperature may result in the denaturing of the enzyme
which was why the test was done at 37°C. This is the body temperature of
humans which led to the formation of amino acids which is absorbed by cells
of the body.

The list of biomes that shows environments from the highest average temperature to the lowest average temperature is desert, swamp, and mountain. Therefore, option C is correct.
What are biomes?Since they belong to certain areas or zones that, due to their geographical characteristics, share a climate, vegetation, and wildlife, biomes provide the primary support for the harmony of nature.
Any biome can include a wide range of habitats because the term "biome" is more general than "habitat." An area's climate and geography determine the biome classification. Communities that have adapted to the unique climate and ecology of the biome make up each one. Depending on the surroundings, they come in a variety of forms. The temperate deciduous biome is the ideal environment for human habitation.

Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.
What is protein?It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.
Protein is made from twenty-plus basic building blocks called amino acids.
Because we don’t store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.
