Answer 1

Answer:

the development of a membrane, enabling metabolism and creating the first cells.

Explanation:

In Abiogenesis (evolutionary biology), the formation of life on earth is described by three (3) main stages and these includes; phase 1, phase 2 and phase 3.

In phase 1, small molecules that comprises of carbon and hydrogen are formed on earth. The second phase is the formation of molecules that can be replicated by themselves and contains informations.

Phase 3 involves the development of a membrane, enabling metabolism and creating the first cells.

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.

Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles such as nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, and vesicles.

The regular sequence of growth and division that cells undergo is called the cell cycle. This cycle makes it possible for the cells found in living organisms to divide and produce new cells.

Basically, there are four (4) phases of the cell cycle and these are;

I. Prophase.

II. Metaphase.

III. Anaphase.

IV. Telophase.

Hazardous air pollution stationary source requirements are known as National Emission Standards for Hazardous Air Pollutants (NESHAP). The term "hazardous air pollutants" (HAPs) refers to airborne contaminants that are known or strongly suspected to be responsible for cancer, as well as other major health issues such birth defects or reproductive problems.

The EPA creates national enforcement programs that are centered on serious environmental concerns and patterns of noncompliance.

Therefore, Radon is naturally occurring gas can be found in certain rocks and soils and is considered a hazardous air pollutant.

Answers

Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.

Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.

Answers

Explanation:

Algae, Mosquito larvae, Minnows, Trout, and Herons are arranged in the following pattern in a food chain.

What is a food chain?

A  food chain is an arrangement of organisms where energy flows from through lower organism to higher organism. Each organism in the chain transfers energy to the other organism present at higher order and the flow of energy goes on.  Biotic factors, algae, mosquito larvae, minnows, trout, and herons are arranged in the following sequence in the food chain.

Algae are the primary producers in aquatic ecosystems which are eaten by mosquito larvae, which are then eaten by minnows. Minnows are then eaten by trouts. Herons, being the largest predator feeds on the trout.

Each organism in the food chain obtains energy from the organisms present at lower trophic level. However, the energy flow decreases at each trophic level, therefore, the organism at higher trophic level receives the less amount of energy.

Therefore, the food chain is created in the following order: Algae, Mosquito larvae, Minnows, Trout, and Herons.

How are the spines on a cactus different from the leaves on an oak tree?
1. They provide nutrient intake
2. They provide heat exchange
3. They reduce water loss
4. They reduce oxygen release

Answers

Answer:

3.

Explanation:

because normal leaves transpire and release water where as spine don't transpire

Answer:3.
Explanation: Cactus spines are basically modified leaves. They defend the cactus against herbivores but also assist in reducing water loss by reducing air flow to the cactus, which provides shade. And due to no leaves the cactus stems are what carry out photosynthesis. In simpler terms, the water on leaves can be lost due to evaporation, but cactus spines don’t.

The _________ was the main opposition group to apartheid in South Africa. Founded in 1912, the group was later banned by the South African government. Group of answer choices Katanga National Congress Mau Mau National Congress African National Congress

Answers

Answer:

African National Congress.

Explanation:

The practice or system of Apartheid was one way the government of South Africa implemented to 'manage' the majority of black people. Though the whites are in minority, they wanted to stay superior. So, the practice of Apartheid gave them the 'scope' for authority, segregating the blacks from them.

The African National Congress, formerly known as the South African Native National Congress, was founded in 1912 by John Langalibalele Dube. The party's aim was to unite all the African people and bring them together as a united nation, irrespective of tribe or background. It later became the main party to oppose the Apartheid policy of the government. After a violent outcome of a peaceful protest, the South African government banned the party in April 1960. This ban was lifted in February 1990.

B.) going down a mountain
C.) going up a mountain
D.) a heavy rainstorm
I think it’s d but I’m not sure :’(

Answers

the answer is most likely going to be c










.

Drop in air pressure takes place when one goes up a mountain.

Altitude is associated with air pressure, that is, with an elevation in altitude, there is a drop in air pressure.

• That is why when one goes up the mountain, the person feels a drop in air pressure.

• The air pressure is indicated with the help of an instrument called altimeter.

• There are two reasons of the drop in air pressure with altitude, that is, gravity and density.

• The high altitude regions like mountains are generally much colder than the regions closer to the sea due to low air pressure.

Thus, the correct answer is option C.
