Describe how an enzyme speeds up a chemical reaction within a cell. (written answer)
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Why are amino acids called amino acids?
Answer:
The name “amino acid” is derived from the amino group and carboxyl-acid-group in their basic structure. There are 21 amino acids present in proteins, each with a specific R group or side chainAll organisms have different essential amino acids based on their physiology.
Answer:
Because they are made of an amino group (NH3) and carboxylic acid group ( COOH)
= amino acid

The respiratory system handles the coming of oxygen to body and out of carbon dioxide from body
what features do root hair cells, epithelial cells, and red blood cells have in common
All of these types of cells have a high surface area-to-volume ratio.
What is the function of RBCs?
Erythrocytes also referred to as red blood cells carry oxygen to your body's tissues. As oxygen is converted to energy, carbon dioxide is released by your tissues. Additionally, your red blood cells carry carbon dioxide to your lungs so you may exhale it.
The process of getting oxygen from your lungs to your body's tissues is carried out by red blood cells. Your tissues use oxygen to make energy and carbon dioxide to expel waste. The carbon dioxide waste is transported to your lungs by your red blood cells, where it is exhaled.
It takes roughly seven days for red blood cells to properly mature and are then released into the bloodstream from the soft bone tissue (bone marrow) of your body. A protein that enables red blood cells to transport oxygen from your lungs and transfer it to other tissues in your body gives them their vivid red color is called hemoglobin.
Therefore, all of these cells have a high surface area-to-volume ratio.

"The lab allowed me to model and observe stream and river processes. Using a virtual model, I compared low and high velocity streams or rivers, low and high gradient streams or rivers, and low and high volume streams or rivers. I found that higher velocity streams or rivers can cause more erosion, as do higher gradient and higher volume streams or rivers. Not only did these factors move more small sediment, they also moved larger pieces of sediment."
Answer:
Explanation:
This lab here allowed me to model and notice the stream and river processes. I found that higher celerity streams or rivers can cause more abrasion, as do higher gradient and higher volume streams or rivers.

Describe four ways that protist get food?
Answer:
There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. The animal-like protists must "eat" or ingest food. Some animal-like protists use their "tails" to eat.

The figure shows two water molecules held together by a/an
bond. (arrow tip)
A. covalent
B.hydrogen
C.ionic
D.van der Waals
Answer:
b) Hydrogen
Explanation:
The figure shows the hydrogen bonding of two H2O molecules. The red atom is Oxygen which is δ−, and the white atom is Hydrogen which is δ+, this is determined by their electronegativity. H2O molecules can form hydrogen bonding when the Hydrogen atom bonds through hydrogen bonding to the oxygen atom and vice versa.
This type of bond is an intermolecular bond

2) Mites
3) Rodents
4) Animals
5) Birds
Explanation:
1) These are significant and significant pests. Insects have three pairs of legs, two pairs of wings, a segmented body, and complex eyes and antennae that are unique to them. Insects are smart, extracting sap from plants, biting plant parts, burrowing into fruits, twigs, and leaves, attacking roots, barks, and blooms, among other things. Larvae, adults, and nymphs are the stages of insect pests that cause harm.
2) These are insect-like organisms with a soft body and four pairs of legs. The colour of these small organisms is red or pastel yellow. They feed on the plant's sap and attack the crops in large numbers.
3) This bug consumes a considerable amount of human food and causes widespread crop damage. They're also to blame for massive grain losses on fields, in warehouses, and in homes.
4) Wild boars, deer, elephants, buffalo, jackals, monkeys, and squirrels are among the animals that inflict direct harm to agricultural plants. They devour the plants and, as a result, squander a tremendous amount of food.
5) Birds devour grains and destroy crop plants. Crows, parrots, and sparrows are among the most common birds that prey on crops.

If a bee is flying in a circle at a constant speed Is the bee acceleratiy
Answer:
If a bee is flying in a circle at a constant speed, is the bee accelerating? YES, the bee is accelerating. Because acceleration is the change in velocity per unit of time, and the bee is constantly changing direction, the bee is also constantly changing velocity and is therefore accelerating.
Explanation:
Hope it helps
Answer:
Yes it is accelerating
Explanation:
I don't know if you mean accelerating but yes (In mechanics, acceleration is the rate of change of the velocity of an object with respect to time.)

Fungus (mushroom) is the living thing in environment. Thus option C is correct.
What are the types of environment ?The surrounding of living organism including both the biotic and abiotic factors called as environment. It may be natural, social, or built environment.
Majority of the environment is composed up atmosphere, hydrosphere, lithosphere, and biosphere.
It can be up microenvironments which is the immediate local surroundings of an organism and secondly macro environments refers to biotic and abiotic factors.
Two common types of environment such as natural or geographical environment, and man-made environment.
Geographical environment include terrestrial environment independent of humankind. For example rivers, deserts, water, oceans.
Man-made environment refers to a social environment. It is completely dependent on human social influence.
For example, city infrastructures, houses, transport and communication etc.
Thus option C is correct.

why organisms need specialised cells and tissues in order to survive
Multicellular organisms require cells to perform various functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures become specialized for specific functions.
What is cell specialization?Cell specialization, also recognized as cell differentiation, is the methodology by which formulaic cells transform into specific cells that perform specific functions within the body.
Cell specialization is especially important during embryonic development.
Cell specialization allows multicellular organisms to express fewer genes in individual cells, protecting genes from mutagen damage.
Cell specialization occurs primarily during embryonic development as a result of cell signaling of cytoplasmic determinants.
Adult stem cells become specialized to various types of stem cells primarily due to gene expression regulation.
Cells in multicellular organisms must perform a variety of functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures evolve to perform specific functions.
Thus, the organisms need specialized cells and tissues in order to survive.

1. A rock sample has a mass of 16 grams:
and a volume of 8 cubic centimeters.
When the rock is cut in half, what is
the volume and density of each piece?
(1) 8 cm3 and 0.5 g/cm3
(2) 8 cm² and 1.0 g/cm3
(3) 4 cm' and 2.0 g/cm3
(4) 4 cm3 and 4.0 g/cm3
1
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
