Question 3
The difference between pectin an amylopectin is that
1. Pectin has more branching
2. Amylopectin has a - 1,4 glycosidic bonds and pectins have a - 1,6 glycosidic bonds
3. Amylopectin has more branching
4. Amylopectin has a - 1,4 glycosidic bonds and pectins have ß - 1,4 glycosidic bonds
The difference between pectin and amylopectin is that amylopectin has more branching than pectin.
What is pectin?"Pectin consists of a complex set of polysaccharides." This has a linear chains of α-(1–4)-linked D-galacturonic acid.This are mainly found in plants.This helps in binding cells together.What is amylopectin?"Amylopectin is a highly branched macromolecule composed mostly of α-(1→4)-d-glucopyranose units, with α-(1→6)-linkages at intervals of approximately 20 units."These are water insoluble.Hence, the correct option is 3. Amylopectin has more branching.

a scientist begins working by trying to explain a natural occurence that is...
1. consistent
2. observable
3. In a lab
4. undetectable
Answer:
Observable
Explanation:
An observable phenomenon leads to an hypothesis.
Answer:
2. observable
Explanation:
The scientific method relies on a scientist being able to study an occurrence and understand it. So, all the occurrences must be observable; otherwise, they cannot be studied. If the patterns are observable then one can follow the scientific method and experiment with the different variables. All science depends on the observable world and the people that study it.

what is one way the gas giants differ from the terrestrial planets?
ANSWERPlanets that are largely comprised of rock, such as rocky or terrestrial planets, are not like gas giants. Unlike rocky planets, gas giants lack a clearly defined surface there is no obvious line separating the atmosphere from the surface. The atmospheres of the gas giants are primarily hydrogen and helium.

The table lists some organelles and functions. Only one pair is correctly matched.
Functions of Organelles
Organelle Function
Nucleus Directs cell activity
Endoplasmic reticulum Breaks down sugar molecules to supply energy
Golgi apparatus Supports and protects organelles in the cell
Lysosome Produces proteins for the cell
Which organelle in the table is correctly matched with its function?
Answer:
I believe the correct answer is nucleus.
Neither endosomes nor lysosomes are found in the nucleus. The nucleus serves as the primary remote control for the cell. It acts as the cell's brain by giving instructions on what to do, how to grow, and when to reproduce.
What is the cell controlling power of nucleus?The nucleus serves as the primary remote control for the cell. It acts as the cell's brain by giving instructions on what to do, how to grow, and when to reproduce. The nucleus of the cell contains the cell's genes.
The nucleus is the area of the cell that manages all of its operations. The nucleus is a membrane-bound, spherical organelle.
Its membrane, known as the nuclear membrane, has nuclear pores that control how materials are transported into and out of the cell. The nucleus' ability to store DNA is its primary role.
Therefore, Nucleus organelle in the table is correctly matched with its function.

By the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. The materials that you examine will differ in molecule size . Some will be larger and some smaller . Formulate an investigative question for this situation .
Answer:
Due to their sizes.
Explanation:
Some materials diffuse through a semipermeable membrane because of their small size which can pass through small pores present in the semipermeable membrane of the cell while on the other hand, some molecules can't diffuse through semipermeable membrane of the cell due to its large size. Glucose, oxygen and sodium are the examples which are smaller in size and can diffuse through semipermeable membrane whereas fats, carbohydrates and proteins are big in size so it can diffuse through semipermeable membrane of the cell.
Answer:
What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?

If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to
denature (become inactive/ stop working)
True
False
Answer:
very true
Explanation:
they dont like change:)
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies.
If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to denature is a true statement.
What are enzymes?The enzymes show the best activity at optimum temperature and pH. When there is a change in the temperature, the structure of the enzyme is changed.Any change in the temperature or pH will result in the breaking of the peptides or disulfide bonds. This will disturb the tertiary structure of the enzyme. At the lower temperature, the enzymes get deactivated while, at a higher temperature, it gets denatured.Thus, we can conclude that the correct option is True.

Which is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

When people receive organ transplants, they often need to take medications that decrease immune responses because * 2 points D. transplanted organs produce their own antibiotics B. antigens present in these organs attack antibodies already present in the blood C. hormones present in replacement organs prevent the synthesis of antibiotics A. transplanted organs contain antigens that can trigger white blood cell activity
Answer:
The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity
Explanation:
The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.

24) is it possible to know the genotypes of the three children in generation 111?
should their shapes be shaded? explain your answer to both questions.
Answer:
The genotype of all children in generation III is Hh. as H comes from dad and h comes from the mother for every case.
yes, their figures should be shaded.
reason :-
The dominant allele Fort this disease is shown by H whereas the recessive trait shown by h.
each offspring in generation III has the genotype Hh
and the presence of one dominant allele is enough to cause the disease.
all children in generation 3 suffer from the disease and so their figures should be shaded
