Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution?

A. The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
B. The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.
D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slits.

A marble dropped from the Foshay Tower in Minneapolis hits the ground at 52 m/s. How high is the Foshay tower?

Answers

Answer:

Height of the Foshay tower is 138 m

Explanation:

Using the third equation of uniformly-accelerated motion under gravity:

v² = u² + 2gh

Where v is final velocity,

u is initial velocity,

g is acceleration due to gravity,

and h is height

v = 52 m/s;

u = 0 (since the marble was dropped from rest at a height above the ground);

g = 9.8 m/s²,

h = ?

(52 m/s)² = 0 + 2 × 9.8 m/s² × h

2704 m²/s² = 19.6 m/s² × h

h = 2704 m²/s² / 19.6 m/s²

h = 138 m

Therefore, height of the Foshay tower is 138 m

Recombinant DNA technology involves which sequence of steps?

Answers

In standard cloning protocols, the cloning of any DNA fragment essentially involves seven steps: (1) Choice of host organism and cloning vector, (2) Preparation of vector DNA, (3) Preparation of DNA to be cloned, (4) Creation of recombinant DNA, (5) Introduction of recombinant DNA into the host organism, (6) Selection

Answer:

Explanation:

Processes of recombinant DNA technology involve isolation of DNA of the desired DNA fragment. In order to cut the DNA with restriction enzymes, it needs to be in pure form, free from other macromolecules. The DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides, and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). The RNA can be removed by treatment with ribonuclease whereas proteins can be removed by treatment with protease.

Different types of selection may occur within a species in response to environmental change. Which of the following would provide evidence that stabilizing selection is occurring in response to environmental conditions?

A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes

Answers

An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes favors stabilizing selection. Therefore, the correct statement is option D.

What is stabilizing selection?

Stabilizing selection is a natural selection favoring intermediate phenotypes over extreme phenotypes. When the environment is stable, individuals with intermediate traits will be more fit than those with extreme traits.

Individuals with intermediate phenotypes have high chances of survival due to stabilizing selection, resulting in an increase in the frequency of intermediate phenotypes and frequency of extreme phenotypes decreases.

Stabilizing selection results in reduction of the genetic variation within a population, as extreme phenotypes are less likely to survive. The reduction in genetic variation results in more homogeneous population.

Therefore, an increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes is a type of stabilizing selection.

What is DNA?

DNA stands for deoxyribonucleic acid.

DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.

It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.

There are basically two types of DNA.

Autosomal DNAMitochondrial DNA

Today, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.

Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.

Thus, DNA is created by the DNA polymerase and unzipped by the DNA helicase.

How do u merge two. Atoms together and. Make a nucleus atirficially

Answers

There are several ways that atoms can combine. In one way, atoms are put together to form things called molecules. To understand molecules, you have to understand what an atom is made up of. Inside the atom, there's things called neutrons, protons, and electrons. The neutrons and protons are all stuck together in the middle of the atom, making up what's called the nucleus. The electrons are much lighter than the protons or neutrons, and they move all around the nucleus. For a picture of this, look at the answer to the question, .

Some atoms, though, want to have more or less electrons around them than they do. So they form things called bonds that let them share electrons with each other. (There are lots of different kinds of bonds, but this is the basic idea.) When they're sharing electrons, they're totally stuck together and become what's called a molecule.
(added by Mike W.: Those types of bonds are called ionic bonds, where one atom grabs an electron from another and the resulting charged ions stick together by electrical attraction. Bonds can also form even between atoms which are just like each other, so that neither ends up with more or less electrons than it started with. Common examples are the oxygen and nitrogen molecules in the air. Here the reason that the atoms stick together is that the electron clouds, described a bit in that link above, can lower their energy by spreading out over two atoms instead of one, for reasons that one can't begin to describe without quantum mechanics. These covalent bonds are very common and often the strongest bonds around.)

Some atoms, though, don't want to have any more or less electrons than they have. So they don't form bonds with any other atoms. (An example of this is Helium.) So they don't bond at all. (Mike W.: What this really means is that every electron is stuck well, in a low energy state. The next state available would have much higher energy. Only very weak bonds can form with other atoms. The reasons why there are particular states around with different energies are also entirely due to quantum mechanics.))

Natural selection is the theory that states that if individuals of different genotypes are differently qualified to live and have viable offspring under prevailing conditions, those genes that promote greater fitness must spread at the expense of others. Natural selection is therefore the process that occurs when more capable traits are inherited from one generation to another due to the interaction between the characteristics of the organism and its environment. The first to propose this theory was Charles Darwin.

Binary fission is a method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves.
Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism

The difference between mitosis and binary fission is that while mitosis occurs in eukaryotes and binary fission occurs in prokaryotes.

Mitosis and binary fission are forms of cell division that duplicate cells. Binary fission occurs in prokaryotes which are the cells that do not contain a nucleus.

On the other hand, mitosis occurs among the eukaryotes which are the cells that have a nucleus. Also, binary fission doesn't include spindle formation in its process which makes it faster than mitosis.
