How does a change in the biodiversity of an ecosystem affect humans?
Answer:
Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

Explanation:
Ocean ridges form at convergent boundary true or false
Answer:
True!
Explanation:
Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.

Transcription and translation, the two main processes involved in protein synthesis, have distinct molecular inputs and outputs. Which statement about inputs and outputs in these processes is true?
A. DNA is an input for the process of transcription and an output for the process of translation.
B. DNA is an input for the process of translation and is not involved in the process of transcription.
C. Messenger RNA is an output for the process of transcription and an input for the process of translation.
D. Messenger RNA is an input for the process of transcription and is not involved in the process of translation.
Answer:
C. Messenger RNA is an output for the process of transcription and an input for the process of translation.
Explanation:
Transcription is where DNA is copied to form RNA. Translation is the process where mRNA is converted to proteins. Therefore mRNA is the output of transcription and the input of translation.
The statement which is true about inputs and outputs of transcription and translation is as follows:
Messenger RNA is an output for the process of transcription and an input for the process of translation.Thus, the correct option is C.
What is Transcription?Transcription may be defined as a process through which a cell constructs an RNA copy in the form of a messenger RNA from a piece of DNA. This biological process of protein synthesis occurs in the nucleus of the cell.
While translation may be defined as a process through which a form of messenger RNA converts into specific amino acid sequences to form a particular protein. This process of gene expression occurs in the cytoplasm of the cell.
In transcription, DNA acts as input while mRNA is output, in translation, this same set of mRNA acts as input while the sequence of amino acids is output.
Therefore, messenger RNA is an output for the process of transcription and an input for the process of translation. Thus, the correct option for this question is C.

1. Which of the following functions is the cell membrane responsible for? (Choose all that apply) containing the cell U protecting the cell regulating the cell's interaction with its surroundings housing hereditary information
Answer:
The First three answers are correct. (The last one refers to the nucleus which is also inside the cell membrane so i don't know if it's correct)
All of the options are correct for the function of cell membrane.
What is cell membrane?The cell membrane is a thin selectively semi-permeable membrane an outer covering of a cell by surrounding cell cytoplasm.
Proteins and lipids are the major components of cell membrane where as the ratio of protein to lipid in cell membrane may vary depending on types of cells.
The most common lipid in membrane is phospholipid, which form a semi-permeable lipid bilayer.
The function of cell membrane is to protect the integrity of the internal environment of the cell, act as a base of attachment for the cytoskeleton in some organisms resulted in support cell and maintain its shape.
It helps in transport of nutrients into the cell and transport of toxic substances out of the cell due to its selectively permeable nature.

Let's bring what you have learned about the carbon cycle, photosynthesis, and cellular respiration and show how they are connected/work together in an ecosystem. Play the role of a carbon atom in an ecosystem. Start with the production, how are you made? And then explain how you transform through different processes. Make sure to include your role in the carbon cycle, photosynthesis, and cellular respiration. There is no set length, as long as you explain the role of carbon in each process.
Answer:
Plants absorb carbondioxide gas from atmosphere whereas respiration releases carbondioxide .
Explanation:
Carbon is present in the atmosphere in the form of carbondioxide gas which is used by the plants in the process of photosynthesis. Plants takes carbondioxide gas from the surrounding air through small openings called stomata and made their own food while on the other hand, carbondioxide gas is released from the body of living organisms in the process of cellular respiration. In cellular respiration, food is broken down with the help of oxygen forming water, carbondioxide gas and energy in the form of ATP molecules.
In the process of photosynthesis, plants produce glucose. They use some of this glucose to grow. They store the rest in fruit and seeds in order to
reproduce. What is the use of this stored glucose in the seed?
Answer:
RESPIRATION, MAKING FRUITS, MAKING CELL WALLS, MAKING PROTEINS, STORED IN SEEDS AND STORED AS STARCH
Explanation:
Glucose molecules together form cellulose, which builds or adds strength to cell walls. Glucose molecules also form carbohydrates. When combined with nitrates from the soil, glucose will form amino acids

they do not obtain energy directly from it. *
Answer:
Energy stems from the sun
Explanation:
Think about it, A plant takes energy from the sun and then a worm eats it soon after a bird eats that worm then when the bird dies its body is fed to fungi or back to plant life. Pretty much the sun is our biggest source of energy
Also The sun is our major source of heat without the sun we would freeze and perish.

Specialized cells are stem cells that turn into cells with specific functions
Specialized cells are differentiate into cells with specific functions.
What is cell differentiation?Cells are the fundamental cornerstones of all life. Numerous numbers of cells construct the human body.
The process by which dividing cells alter their functional or phenotypical type is known as cell differentiation. All cells, it is assumed, derive from stem cells and acquire their functions as they mature.
In response to antigen exposure, some differentiation occurs. Differentiation alters a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals significantly.
These changes are primarily the result of highly controlled changes in gene expression and are the subject of epigenetic research.
Mesenchymal stem cells, epithelial stem cells, and muscle satellite cells are the three types of differentiated cells.
Thus, the answer is differentiation.

The statement that accurately describes the role of the light-independent reactions is as follows:
Transferring chemical energy to high-energy sugars.Thus, the correct option for this question is B.
What is a Light-independent reaction?The light-independent reactions of photosynthesis occur in the stroma of the chloroplast in the presence of light itself. Rubisco is involved in this type of reaction. The Final product of this reaction is the production of carbohydrates. It also involves the fixation or reduction or assimilation of Carbon dioxide.
In the light-independent reaction, the light energy is transformed into chemical energy which is then transferred to the high-energy sugars component in order to derive energy for metabolic activities. The storage of high-energy sugar for future use when direct sugar is not available is also accomplished in this reaction.
Therefore, the correct option for this question is B.
