What is natural selection?

Darwin employed natural selection for the first time. He discussed the parallels and differences between the various creatures. These differences are sometimes referred to as variety. The process by which nature chooses the most adaptable and compatible organisms for evolution is known as natural selection. The organisms in nature face some difficulties. Climate change, food insecurity, and natural disasters including earthquakes, floods, and lightning are a few examples of these difficulties.

Answer:

The best answer of how animals release energy needed for growth and repair is ( C ) :  A series of chemical reaction during cellular respiration

Animals need energy to function effectively daily and also to repair. one way by which Animals get such energy is through cellular respiration.

during cellular respiration the series of chemical reaction that leads to the release of energy follows this pattern.

Consumed food ( sugar/glucose molecules ) are broken down

The energy released  from the breakdown is then transformed into ATP energy

The transformed ATP energy is then used for Cellular activities  ( growth and repair of animal cells )

Photosynthesis and Cellular respiration are have similar process but the former ( photosynthesis ) occurs in plants not Animals.

Hence we can conclude that animals release energy needed for growth and repair through a series of chemical reaction during cellular respiration.

Answer:

Fructose is the sugar in organic fruits that gives energy to cells and Glucose is the other one.

Explanation:

Glucose is the bad one for you body because it is unnatural sugar. Which means it sends energy to your body but the energy is used up very quickly. It is like cafience but it's baby.

The Cellular Respiration worksheet is given in the image attached.

Cellular respiration is seen as a metabolic process that occurs in cells, where organic molecules are broken down to release energy in the form of ATP (adenosine triphosphate).

This process involves three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. During glycolysis, glucose is broken down into pyruvate, which then enters the Krebs cycle, where it is further broken down to release energy-rich electrons.

Therefore, These electrons are then passed down a series of electron transport chains to produce ATP through oxidative phosphorylation. Cellular respiration is a vital process for all living organisms, as it provides the energy needed for various cellular processes and activities.

relaxed packaging of the chromatin and increased transcription.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.

Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Gibberellic acid (GA) plays a crucial role in a-amylase production and germination. GA stimulates the synthesis and release of a-amylase enzymes, which hydrolyze starch into sugars during germination. Experimental studies have demonstrated that the application of GA accelerates a-amylase production and enhances germination in various plant species

In terms of a-amylase production, GA stimulates the synthesis and release of this enzyme. a-amylase is responsible for breaking down starch into simpler sugars, which are then utilized by the plant for growth and development.

Studies have shown that applying GA to plant tissues or seeds results in an increased production of a-amylase, facilitating the conversion of stored starch into energy-rich sugars.

Regarding germination, GA is involved in breaking seed dormancy and promoting the growth of the embryonic plant.

It stimulates the production of hydrolytic enzymes like a-amylase, which enable the hydrolysis of starch reserves in the endosperm, providing the energy needed for germination and seedling establishment.

Additionally, GA helps in cell elongation and division, promoting the growth of the embryo and the emergence of the radicle.

Evidence for GA's role in both processes includes studies where the exogenous application of GA to seeds or plant tissues has been shown to enhance a-amylase production and promote germination.

Conversely, inhibiting GA synthesis or action results in reduced a-amylase activity and impaired germination. These findings support the critical involvement of GA in both a-amylase production and germination processes in plants.

Distance & Time

Explanation:

Speed is described by distance

Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyte. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir. Color the reservoir grey and the flagellum black.

The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. Color the eyespot red.Euglena can also gain nutrients by absorbing them across their cell membrane, hence they become heterotrophic when light is not available, and they cannot photosynthesize.

The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm type fashion. Color the pellicle blue.

In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus. Color the nucleus purple, and the nucleolus pink.

The interior of the cell contains a jelly-like fluid substance called cytoplasm. Color the cytoplasm light yellow. Toward the posterior of the cell is a star-like structure: the contractile vacuole. This organelle helps the cell remove excess water, and without it the euglena could take in some much water due to osmosis that the cell would explode. Color the contractile vacuole orange.

The three correct answers are:

B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments. This process leads to the beautiful fall foliage colors observed in maple trees. As the weather gets colder, the breakdown of chlorophyll exposes the underlying pigments, creating vibrant red, orange, and yellow leaves.

C. Xylem and phloem fill with ions and organic substances that prevent freezing. In response to increasing cold weather, the tree transports ions and organic compounds into the xylem and phloem. These substances act as antifreeze agents, preventing the freezing of sap and ensuring the circulation of nutrients and water within the tree.

D. Meristems form thick scales to protect next year's buds from cold winter temperatures. The meristems, which are the regions of the tree where new growth occurs, undergo changes in response to the approaching cold weather. They form protective scales around next year's buds to shield them from the harsh winter conditions, ensuring their survival and future growth.

Following diagram shows the transport of protein.

1- The nucleus is involved in teh formation of mRNA which is used to send message to the ribosome about what kind of protein is used to synthesize

2- and 3- Endoplasmic Reticulum(ER), Rough ER has the ribosomes on their surface, which are involved in teh formation of protein.

4- They are the vesicles from the RER

5- It is the Golgi body or Golgi complex or golgi apparatus or simply Dictyosomes. They are used in the packaging of the protein, gives the protein finishing touch before they move out from the cell. They like ER has canalicular system with sacs but they are parallel arranged, flattened membrane bounded with lack of ribosomes. They have two faces. One is receiving face which receives the vesicles from the Endoplasmic reticulum called cis face. The other is shipping face which releases packaged protein into the cytoplasm ready to go outside from the cell.

6and 7- They are the vesicles from the golgi bodies.

8- Vesicle diffuses with the cell membrane through which the protein is moving out from the cell, the process called exocytosis.
