Hello Im Here To Answer Your Question! (Big Idea)Reptiles, birds, and mammals all share similar
traits, but other, specialized characteristics classify these
animals into different groups.
Explanation:
The large eyes and ears of this
eastern tarsier make it an excellent
nocturnal hunter. These unusual
mammals are primates and are
closely related to modern monkeys.
About the same size as a kitten, a
tarsier has strong hind legs similar to
those of frogs. The tarsier’s eyes
cannot move but it has a full range of
view because it can rotate its head
almost 360 degrees.Reptiles, birds, and mammals are all amniotes. Recall that amniotes develop
inside a membraneous sac. This sac contains everything an embryonic vertebrate needs to grow and prepare for the world outside. In some amniotes, the
sac is contained inside the mother’s body. In other amniotes, a tough outer
shell protects embryos as they develop outside of the mother. This shell is
semipermeable, which means that it allows gases such as oxygen and carbon
dioxide to pass through but prevents the embryo from drying out by holding
water inside.
An egg is a completely self-sustaining container
that provides enough energy and nutrients to
enable the embryo to mature. The illustration in
Figure 1.1 shows the different membranes found
inside an amniotic egg. The egg you may have
eaten for breakfast this morning was formed with
all of the necessary membranes and nutrient stores
to support a chicken embryo. But because the egg
was never fertilized, the genetic composition of
the egg remained haploid and did not develop into
an embryo.
The development of the amniotic egg was an
important adaptation because it allowed vertebrates
to reproduce on land. Without the self-contained
source of energy and water, an egg needed to
develop in water or else the embryo would dry out.
Predict What happens when all of the resources that
are stored inside the egg are used?
In an American football game, linebacker with a momentum of 121 kg m/s tackles
a quarterback who had a momentum of -80 kg m/s. After the tackle, the linebacker
has a momentum of 72 kg m/s. If momentum was conserved, what is the momentum
of the quarterback after the collision?.
-80 kg m/s
41 kg m/s
121 kg m/s
-31 kg m/s
The moment of a system results from adding the vectorial moments of each object composing the system. According to the law of conservation of momentum, the initial moment is equal to the final moment. D) -31 kg m/s.
What is the momentum?First, let us remember that momentum or lineal momentum is a motion quantity. In physics, it is the fundamental quantity that characterizes the motion of any object.
The momentum is a vectorial quantity calculated as the product of the object mass by its lineal velocity ⇒ mv.
The total lineal moment of a system constituted by a group of objects, is the sum of the vectorial moments of each of the objects.
In an isolated system (like crushes, explosions, and collisions), the moment remains constant through time. This is the law of conservation of momentum. The initial moment is equal to the final moment ⇒ Pinitial = Pfinal
In the exposed example,
linebacker and quarteback are the objects in this system. each object (players) has a vectorial moment (121 kgm/s and -80 kgm/s)Pinitial = Pfinal.121 kgm/s + (-80 kgm/s) = P initial
72 kg m/s + X = P final
Pinitial = Pfinal
121 kgm/s + (-80 kgm/s) = 72 kg m/s + X
Now, we just need to clear X to determine the momentum of the quarterback after the collision.
121 kgm/s - 80 kgm/s - 72 kgm/s = X
121 kgm/s - 80 kgm/s - 72 kgm/s = - 31 kgm/s
Option D is correct.

What 3 regions are used for auditory?
The human auditory is divided into 3 parts:
1. The outer ear- involving the externally visible portion of the auditory system along the ear canal.
2. The middle ear - this part transmits sound vibration from the end of the ear canal to the cochlea.
3. The inner ear- the primary organ of the inner ear is the cochlea, the cochlea is responsible for transmitting sound information to the nervous system.
Is stored energy kinetic or potential?
We have to consider that kinetic energy is the one which in-movement bodies have, like atoms, or molecules. So the stored energy could be known as potential energy since it's a reserve the cells or other bodies, materials, atoms, or molecules can use to develop a determined process.
Explain how the Meselson-Stahl experiment contributed to our understanding of DNA replication, and describe that process.
REAL ANSWERS ONLY! NO LINKS!
Meselson-Stahl's experiment contributed to our understanding of DNA replication because the use of radioactive nucleotides showed that one DNA strand is synthesized in each round of replication while the other chain remains unchanged, which is known as semiconservative replication.
What is semiconservative replication?In genetics, semiconservative replication refers to the process by which DNA is duplicated during the process of DNA replication. In semiconservative replication, one DNA chain is conserved in intact conditions while the other one is synthesized in the final double helix DNA molecule.
Meselson-Stahl's experiment contributed to the discovery of the semiconservative nature of DNA replication by observing that only one radioactive chain was added to each round of replication.
Therefore, with this data, we can see that the semiconservative replication of the double helix DNA molecule is a fundamental process associated with DNA replication which was discovered by Meselson-Stahl's experiments.

In Biology, group behavior refers to actions made by one organism that help to the survival of another organism in the group.
Some examples are:
• Meerkats have lookouts for predators
,• Bees have designated individuals for different tasks, such as foraging for food or defending the nest.
,• Sharing food resources.
,• Migrating birds fly in formation to conserve energy.
,• Fish swim in schools to avoid predators
One consequence of the organisms living in groups and doing group behaviors is that is easier to find a mate, given that they don't have to travel to find another individual of the same species.
This means that B) having an easier time finding mates, would be the right answer.

Which two stages are most responsible for the genetic variation observed within a species?
A Anaphase I and Prophase I
B Anaphase II and Metaphase II
C Metaphase I and Metaphase II
D Metaphase I and Prophase I
Independent Assortment, Random Fertilization and recombination takes place during Metaphase I and Prophase I. Therefore, option (D) is correct.
What causes genetic variation in a species?Prophase I is when recombination or crossing across happens. Gene by gene, identical chromosomes—1 from each parent—pair along their lengths. Chromosomes break along their length, reunite, and exchange some of their genes. The chromosomes now contain a distinctive collection of genes. This causes genetic variation.
Random Fertilization and Independent Assortment in Metaphase I
The tetrads travel to the metaphase plate during metaphase I with their kinetochores pointing in opposite directions. The homologous pairs randomly align themselves with the equator. This occurrence is the second process that modifies gametes or spores.

Since we now that the change in the first positicion C for a Timine allowed the emergence of lineages A and D, we could say its inverse for the emergence of C and E, that is 1 - T -> C. I attempt that since A and D, are a sister clade with C and E, so we the only change there would be the first base. In the branching point behind A - D; C - E, we could propose a change that precede both clades, of course this is a guess and also it is arbitrary. We could say, 2 - T -> C, that is, in the second position, both couples A - D; C - E have a Citosyne.Therefore we would propose that the branch behind the bifurcation (BBB) following A-D; C-E has in its first two bases -CT-. From this point, we move to the branching point that precedes the clades E-H, and B-G. Let's propose that a change in the third base occurs, that goes from A to G. So we would have in BBB this sequence: -CTA- and in the point we are actually inferring CTG. Then, behind the clade F-H, let's propose a change in the fourth position, that goes from G - A. Following the above procedure, the change behind the B - G clade will be 4 - A to G. So for example in the clade A-D we will have this DNA sequence -TCA. In the clade C-E the DNA sequence will be -CCA-. In the clade F-H -CTGA- while in the clade B-H -CTGG-

Membrane bound organelles that modify, package and move macromolecules such as proteins and lipid molecules in eukaryotic cells are collectively known as the endomembrane system. The various functions of the endomembrane system are:
1,) Protein synthesis: This occurs in the rough endoplasmic reticulum. It contains ribosomes, which help to synthesize secondary structures in proteins.
2.) Protein modification and sorting: This is also done in the rough endoplasmic reticulum. The flattened membrane disks and cisternae perform protein modification.
3.) Lipid synthesis: The smooth endoplasmic reticulum in the liver produces steroid hormones like testosterone and oestrogen from other steroids and lipids.
4.) Macromolecule digestion: This happens in the lysosome. The lysosome is highly acidic and contains enzymes that aid in macromolecule digestion.
5.) Autophagy: This is the process in which damaged cells and protein are eaten or damaged by the lysosome. The macromolecules are broken down and reused by the cell.
6.) Cisternal maturation: It takes place in the Golgi apparatus.
7.) Calcium ion storage: Calcium ion is stored in the smooth endoplasmic and is secreted into the cytosol when it's needed.
8.) Poison detoxification: The smooth ER in the liver detoxifies substances from digestion. It does this by removing the lipid part and making the substance hydrophilic in order to be excreted by the body.

2) Nucleic acid monomers are called nucleotides; protein monomers are called amino acids.
Explanation: Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and are thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Carbon, hydrogen, oxygen, nitrogen, and phosphorous act as the building blocks for nucleic acids. and the five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus.

an enzyme is specific. this means
Enzymes are said to be specific because an enzyme binds to only one or one group of substrates for its activity.
The enzyme's specificity is a property that indicates how restricted the enzyme is in its substrate selection; There would only be one substrate for a completely unique enzyme. Specificity is the capacity of an enzyme to select a specific substrate from a variety of chemically similar compounds. Specificity is a molecular identification process due to the complementary structural and conformational properties of the enzyme and substrate. Since the specific substrate must fit into the enzyme's active site before catalysis can take place, only well-designed molecules can be enzyme substrates; An enzyme will frequently react with a single naturally occurring molecule or substrate.
