Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
answer:
a balance and a graduated cylinder
Explanation
Density is mass per unit and it is property characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.
For a student to measure the density of seawater he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample and then a graduated cylinder to determine the volume.

Charles Darwin, Charles Lyell and Alfred Russell Wallace all contributed to the theory of
evolution. Which statement best explains how support for this theory was obtained from the
scientific community?
Group of answer choices
Each scientists dissected different species from different parts of the world, then compared and shared their findings with each other.
Many scientific observations, related to biogeography and comparative anatomy, were made, documented and shared.
Together the scientists analyzed and compared cave drawings of various species of prehistoric animals from different parts of the world.
Each scientist worked in isolation to experiment on fossils and prove their beliefs regarding evolution. Yes
They made documented and shared many scientific observations related to biogeography and comparative anatomy . So, the correct option is (C).
What is Theory of Evolution?The theory of evolution, also called the "theory of evolution by natural selection", was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.
Darwin further stated that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this theory, each species has its own distinct lineages or genetic differences that come from a common ancestor, gradually accumulating over a very long period of time.
This theory explained that birds had moved from the mainland to the islands, and that species gradually evolved to fit their new environments. Natural selection occurs because organisms in a population usually have randomly occurring gene variations and mutations that affect adaptation.
Thus, they made documented and shared many scientific observations related to biogeography and comparative anatomy . So, the correct option is (C).

Which statement describes Mendel’s hypotheses regarding gametes?
A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.
Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
Thus, option B) is the right answer.
Answer:
B.

The complex structures of DNA and protein found in the cell nucleus are mitochondria. nucleoplasm. histones. nucleases. chromosomes.
Answer:
chromosomes
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
What colors of light are absorbed? Which color is not absorbed?
Answer:
All colour except which is already present in the body.
Explanation:
The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.
Examine the mechanism of carbonic anhydrase. If the Zn2 were removed from the active site, and replaced with either Cu , Cd2 , or Fe3 would you expect the enzyme to still be functional
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.

a. The P/O ratio of NADH is the mitochondria is _____________.
b. This means protons are pumped across the mitochondrial membrane by each NADH oxidized starting with complex The P/O ratio of FADH2 in bacteria is_____________.
Answer:
a). 2.3
b). 1.5
Explanation:
The P/O ratio stands for the[tex]\text{ phosphate / oxygen ratio}[/tex] in the cells. The P/O ratio is defined as the [tex]\text{amount of}[/tex] [tex]ATP[/tex] which is [tex]\text{produced from the movement}[/tex] of the two electrons by a defined electron transport chain and it is terminated by the reduction in the oxygen atom.
The P/O ratio of NADH in mitochondria [tex]10/(3.3 + 1) = 10/4.3 \approx 2.3[/tex]
The estimated P/O ratio for [tex]$FADH_2$[/tex] = 1.5

If a bacterial isolate show intermediate to moderate resistance to an antimicrobial, how might this drug still be successfully used in the treatment of this microbe
Answer:
Due to its effectiveness.
Explanation:
This drug still be successfully used in the treatment of this microbe because of its effectiveness on the microbes. All the microbes did not got resistance against the antimicrobial chemical and they are not full proof from the antibiotics so that's why the antimicrobial are used in the treatment of microbes. If all the microbes attain resistance against antimicrobial drug so it can't any affect on the microbes.
