(PLEASE HELP )Read the passage below. Highlight the concerns of the plaintiff. Then answer the question to the right.
Recently, the Supreme Court of the United States reversed a lower court ruling that allowed a company to patent DNA sequences for two cancer genes. The patent prevents other scientists from using these DNA sequences for any reason. The company uses the DNA sequences to market kits used to identify the two types of cancer in humans. The company claims that the gene sequences are its intellectual property. it's owner feels that allowing other people to access the sequences will harm his company financially because the search for the gene sequences was very expensive.but the plaintiff in the case argue that Gene sequences are products of nature that cannot legally be patterned the plaintiff explain to the judge that the kids are very expensive as a result some patients who need these tests cannot afford to have them done.

Explanation:
4. Some early mornings , dew drops can be found on grass or a car parked outside,
but not on other materials such as the sidewalk. Why is that?
the nighttime temperature on grass and the car went below the dew point, but
the temperature of the concrete did not drop enough to reach the dew point
level
temperature on the grass and sidewalk were both above the dew point levels all
night
the relative humidity of the air above the grass was higher than it was above the
concrete
none of the above
Dew drops can be found on grass or a car parked outside but not on other materials such as the sidewalk because; The nighttime temperature on grass and the car went below the dew point, but the temperature of the concrete did not drop enough to reach the dew point level.
Definition:
The dew point is simply defined as the temperature below which the water vapour in a given volume of air at a constant pressure will condense into liquid water. More specifically, the dew point is the temperature at which the air is saturated with moisture.From the definition above, it is evident that the fact that the nighttime temperature on grass and the car went lower than the dew point temperature is responsible for the condensation of water vapour on grass and the car as opposed to the case in Concrete.

Answer:
Here is the answer to your question.
Explanation:
Chlamydomonas: Motile unicellular algae, generally oval, cell wall is made up of a glycoprotein and non-cellulosic polysaccharides instead of cellulose, two anteriorly inserted whiplash flagella, contractile vacuoles are near the bases of flagella.
Amoeba: Amoeba is a unicellular organism found in stagnant water, the size of amoeba is 0.25, they move with the help of a finger-like projection called pseudopodia, the cytoplasm is differentiated into two parts, the outer portion is ectoplasm and the inner portion is called endoplast, amoebae are eukaryotes whose bodies most often consist of a single cell.
Paramecium: Paramecia cells are characteristically elongated, Paramecia are eukaryotes, asexual reproduction (binary fission), sexual reproduction (conjugation), autogamy (self-fertilization).
Diatom: Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule.

Answer:
Explanation:
As you know that the earth has two types of motions,
namely rotation and revolution. Rotation is the
movement of the earth on its axis. The movement of
the earth around the sun in a fixed path or orbit is
called Revolution.
The axis of the earth which is an imaginary line,
makes an angle of 66½° with its orbital plane. The
plane formed by the orbit is known as the orbital plane.
The earth receives light from the sun. Due to the
spherical shape of the earth, only half of it gets light
from the sun at a time (Figure 3.2). The portion facing
the sun experiences day while the other half away from
the sun experiences night. The circle that divides the
day from night on the globe is called the circle of
illumination. This circle does not coincide with the
axis as you see in the Figure 3.2. The earth takes about
24 hours to complete one rotation around its axis.
The period of rotation is known as the earthday. This is
the daily motion of the earth.
2021–22
MOTIONS OF THE EARTH 19
Figure 3.3 : Revolution of the Earth and Seasons
What would happen if the earth did not rotate? The
portion of the earth facing the sun would always
experience day, thus bringing continuous warmth to
the region. The other half would remain in darkness
and be freezing cold all the time. Life would not have
been possible in such extreme conditions.
(ii) Describe an experiment he could carry out to show that auxin causes bending of a
shoot.
Answer:
Illumination results auxin moving to the dark side of stem tips. As this auxin diffuses down the dark side of the stem, the cells respond by enlarging. This causes the plant to bend toward the light.

Explanation:
Sickle-cell anemia is a genetic blood disorder. Red blood cells normally have a round shape and pass easily through small blood vessels as they deliver oxygen to the tissue. But in people with sickle-cell anemia, some red blood cells are shaped like a sickle, or a "C." The red blood cells with this sickle shape do not live as long as healthy, round blood cells.
The sickling of red blood cells is thought to be due to problems with the hemoglobin gene. The unusual behavior of the hemoglobin causes rigid fibers of protein to form in the cell membrane, leading to a decrease in its flexibility and the change in cell shape. These rigid, deformed cells are more likely to rupture or get stuck in small blood vessels, creating a blockage. When blood flow to tissues is interrupted, this can lead to long-term damage to organs and even cause death.
1. a) Based on the information above, what are at least two changes that take place in the red blood cells of individuals with sickle-cell anemia? (2 points)
it delivered oxygen easily
in sickle it cause problem
Explanation:
it because their blood cell is not spherical

what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

during dna replication the chromosomes contract and the identical halves are called
Answer:
Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.
