how do the villi and microvilli maximize the ability of the intestine to absorb nutrients?
Answer:The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.

what is the highlighted number ?
Answer:
I think it is the atomic mass, or the atomic weight.
Explanation:
The number above the symbol is the atomic mass (or atomic weight). This is the total number of protons and neutrons in an atom. The number below the symbol is the atomic number and this reflects the number of protons in the nucleus of each element's atom.

What types of solid waste do you produce in your home ?what could be done to each type and what goes to the disposal site or dumpsite
Answer:
Types of solid watse we produce in your home is plastic cups, metal forks and spoons, and also glass plates. We could recycle these items, so they can become other new items when we are finished.
Solid waste are described as abandoned waste materials resulting from human and chemical activities. Solid wastes could include used plastic materials, rubber, metals, glass and other materials classed as useless.
In Homes, solid wastes usually include used plastic, shattered glass, metal objects and so on. Plastic wastes and metals could be recycled and refined to make rubber and aluminium spare parts, hence, serving as raw materials.Therefore, since solid materials take very long to Decay, hence recycling of the waste and their use in organic products are always good means of disposal.

Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
The green trait is the dominant trait.
The offspring will inherit one allele from each parent.
The offspring will have both green and yellow seeds.
Each offspring will have a unique set of alleles.
Answer:
The offspring will inherit one allele from each parent
Explanation:
Just did EDGE
The statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.
What is an allele?An allele is a given gene form, diploid organisms inherit two alleles for gene locus, one from each parent.
A diploid individual can be for a given gene locus:
Homo-zygousHeterozygousAn individual is homo-zygous when it inherits the same allele or gene variant for a particular gene locus.
Conversely, an individual is heterozygous when it inherits different alleles for a given gene locus.
In conclusion, the statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

What is Chargaff's Rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.
A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.
C. Yes, because the number of atoms of each element is the same on both sides of the equation.
Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.
