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.

Answer:

What is Fungus (mushroom)

Explanation:

The living body of the fungus is a mycelium made out of a web of tiny filaments called hyphae. The mycelium is usually hidden in the soil, in wood, or another food source. A mycelium may fill a single ant, or cover many acres.

Air,water and soil may well be a place living things exist in, ecosystem, but they are in no way living.

Fungus (mushroom) is the living thing in environment. Thus option C is correct.

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.

Answer:

Antibiotic resistance is one of the most urgent threats to the public’s health. Antibiotic resistant bacteria can cause illnesses that were once easily treatable with antibiotics to become untreatable, leading to dangerous infections. Antibiotic-resistant bacteria are often more difficult to kill and more expensive to treat.

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

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.

Explanation:

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.

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.

I think it's the last one, photosynthesis takes place in all plant cells, and respiration takes place only in leaf cells, but im not 100% sure

Explanation:

Answer: last one

Explanation:

All of these types of cells have a high surface area-to-volume ratio.

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.

Answer:

I think the answer is C

Explanation:

The scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

Cell division may be defined as the process by which a parent cell divides into two or more daughter cells.

The stretching of a cell to allow for more fat storage is usually done by the process of cell growth, but not by the process of cell division.

Therefore, the scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

Answer:

1) Insect

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.
