Answer:
1.They act as a catalyst
2.Enzymes are proteins
3.They are affected by Ph
4.They are affected by temperature
Explanation:
1.Enzymes act as a catalyst because they either speed up or slow down the rate of a reaction
2.They are proteins because they are made up of 20 amino acids
3.Enzymes are affected by temperature, if the temperature increases, the reaction rate increases. However if the temperature continues to increase, the shape of the active site changes.If the temperature is below preffered temperature range,the rate of the reaction becomes slower,but the shape is not denatured.
they can also speed up reaction times but remain the same while doing so
tempurures and ph can affect them

The enzyme changes the substrate to create a _______.
Answers
Answer: an enzyme products complex.
Explanation:
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex.
A statement in the introduction read, “All other factors remained the same between the two groups.” Make a list of factors that must remain constant in the experiment.
Answers
The factors that must remain the same in an experiment are known as control variables.
In order to conduct a proper experiment, there must be 3 kinds of variables. These are:
Dependent variableIndependent variableControl variableA dependent variable is a variable that the experiment seeks to observe, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable.
The variables referred to in the question are control variables. Control variables are the factors that must remain constant in an experiment. This is to ensure that when we measure a change in the dependent variable, we know to attribute it to the correct cause of the change. The presence of control variables helps to ensure a valid experiment and limits the influence of other factors on the outcome.

Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have three legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.

Explain why men should not accuse women of not delivering male child for them
Answers
Men should not accuse women of not delivering a male child for them because they are not responsible for determining the gender of the child. It all depends on the fusion of chromosomes.
How zygote is formed?The Zygote is formed after the successful fusion of male and female gametes.
Women bear both XX chromosomes, while men bear one X and one Y chromosome. It is a biological phenomenon of fusing these sets of chromosomes and determining the gender of the child.
Therefore, it is well described above.

Answers
For something to be alive, it has to have essential characteristics. Some non-living elements share some of these characteristics with living things, but not all of them. That is what distinguishes one from the other.
The characteristics that all living things have are:
organization; sensitivity; growth; reproduction; homeostasis; and metabolism.
As regards organization, the minimum unit of life is the cell. For something to be a living thing, it has to be a cell or have multiple cells. They have organelles and organize to perform different actions.
The following characteristic is sensitivity, which means that the thing has to react to a stimulus by giving a response.
Living things grow. In other words, they increase in size thanks to the elements that they take from the exterior and process them taking what they need to grow. To do so, they use metabolism.
Metabolism is the combination of catabolism( the elements that the organism destroys) and anabolism( the elements that the organism builds). Metabolism is also essential for homeostasis. These are the different reactions that an organism has to have a balance.
The last essential characteristic is reproduction. Living things have to reproduce themselves, there are different methods, and they depend on the type of living thing that they are.
In conclusion, fire is not a living thing because it does not have cells that can have metabolism, sensitivity, homeostasis, and it can not reproduce itself.
A living thing has six main characteristics:
organization sensitivitygrowthreproduction homeostasis metabolismEven though the fire seems like a living thing because it is consuming wood, making noises, and moving, as many living things do, it is not alive because it does not have cells. As it does not have cells, it can not have homeostasis, react to stimuli, or grow as cells do. It might look like a living thing, but it is not since it does not have the six characteristics that every living thing has.

Which of the statements below correctly compares features of plant and animal cells?
Plant cells have a cell membrane, while animal cells have both a cell wall and a cell membrane.
Plant cells have ribosomes only on the rough ER, while animal cells have ribosomes in the cytoplasm.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles.
Plant cells have chloroplasts but no mitochondria, while animal cells have mitochondria.
Answers
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.
What are vacuole?Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole. The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.
Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.
Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon.
