Answer:

(image 1) Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. As waves attack the shore, headlands are eroded, producing steep sea cliffs. The waves vigorously attack the portion of the cliff near sea level where joints, fissures, and softer strata are especially vulnerable. The cliffs are undermined and caves are formed. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

Answer:

Chlorophyll

Pigment

NADP+

Carrier

Explanation:

Photosynthesis is the process where green plants synthesize their food in form of sugars using sunlight energy. Photosynthetic process occurs in two stages namely: Light dependent stage and Light independent stage.

In the light dependent stage, which occurs in the thylakoid lumen, cells capture the energy of sunlight using CHLOROPHYLL, a type of PIGMENT found in the chloroplast. However, photosynthesis also relies on a compound called NADP+, which serves as an ELECTRON CARRIER that accepts electrons to become NADPH and transfers its stored high-energy electrons.

Answer:

During Photosynthesis, cells capture the energy of sunlight using chlorophyll, which is a type of  pigment.  

Photosynthesis also relies on a compound called  NADP+ which is an electron carrier / donor that accepts and transfers high-energy electrons.

Photosynthesis involves the conversion of light energy from Sunlight into Chemical energy. Photosynthetic organisms use this process to produce their food.

The light rays are captured by a green pigment called Chlorophyll which helps to catalyze the reaction of Carbon dioxide and  water to produce Sugar and Oxygen.

The NAD+ found in the chloroplast which produces the chlorophyll  is an electron carrier which accepts and transfers high energy electrons in order to ensure the process takes place.

Amylase; salivary; esophagus; pepsin; proteins; fats; villi.

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms. Also, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.

The digestion of food begins in the mouth by the action of the enzyme amylase secreted by the salivary glands. This enzyme begins the breakdown of starch. When you swallow, the bolus of food moves down the esophagus by rhythmic muscular contractions called peristalsis. In the stomach, the action of the enzyme pepsin and hydrochloric acid aid in the breakdown of proteins. After leaving the stomach, the acidic mixture of partially digested food, called chyme, enters the first part of the small intestine, the duodenum. Here digestion is completed by the action of enzymes from the pancreas, and bile, which is produced by the liver. Bile aids in the breakdown of fats. The pancreas contributes bicarbonate ions to neutralize the acidic chyme, as well as digestive enzymes (proteases, amylase, and lipase). In the small intestine, numerous tiny projections called villi are responsible for absorption of nutrients. The primary function of the large intestine is to reabsorb

Answer:

pollination

Explanation:

edg 2021

The pollination process of angiosperm reproduction often requires insects or other animals to take place, hence option D is correct.

The transfer of pollen from the anthers to a stigma of the same species, followed by the germination and expansion of the pollen tube to the micropyle of the ovule, are all necessary for effective pollination.

Wind, water, and animals, particularly insects and birds, all contribute to pollen transmission. The union of these male and female gametes occurs during pollination.

Pollen from the male anthers is picked up by the wind or other creatures, particularly insects and birds, and transported to the female stigma.

Therefore, pollination depends on other factors to transfer the pollen because pollen cannot travel alone from the anthers to the ovules.

Explanation:

i got it right on the test

Answer:The correct answer is D. Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.

This is the structural relationship between genes, chromosomes, and DNA. The DNA molecule is the genetic material that carries the instructions for the development and function of all living organisms. It is made up of two complementary strands of nucleotides, which are the building blocks of DNA. Each chromosome contains one long DNA molecule, which is tightly coiled and packaged with histone proteins to form a structure called chromatin. Genes, which are the functional units of DNA, are located at specific positions along the chromosome and are composed of specific segments of the DNA molecule. The genes contain the instructions for making proteins, which are the building blocks of the body and play a crucial role in the development and function of all living organisms.

This answer is supported by the fact that chromosomes are the structures in cells that carry the genetic information in the form of genes, and that genes are made up of DNA which is a long molecule containing the genetic code.

In the induced-fit model of substrate binding to enzymes, the correct statement is: "when the substrate binds, there is a conformational change in the enzyme, and the active site changes its conformation to fit the substrate.

According to this hypothesis, the interaction between the enzyme and substrate is initially only moderately strong, but as soon as the substrate hits the active site, it causes the enzyme to change shape, resulting in a closer match. The enzyme's conformational change enables the active site to better match the shape and chemical characteristics of the substrate, which speeds up the chemical process.

The induced-fit model makes no mention of the aggregation of many enzyme molecules. Additionally, the active site modifies its conformation to match the substrate rather than the substrate changing its conformation to fit the active site.
