Christopher Columbus used the presence of suspended seaweed in the ocean to
determine how far away he was from the coast of the Africa. Seaweed, or kelp, is
placed under the Protista kingătom. What type of protist did Columbus see?
a)protozoa
b) slime mold
c) water mold
d) brown algae
Brown algae is the type of protist Columbus saw. Therefore, option (D) is correct.
What are brown algae?Seaweed is a type of brown algae, which is a type of protist that belongs to the kingdom Protista. Brown algae are large, multicellular algae that grow in the ocean and are often found in shallow, warm waters. They have a complex structure and are made up of many cells that are organized into tissues and organs. Brown algae are photosynthetic, meaning they use sunlight to produce energy and nutrients, and they are an important source of food and habitat for many marine organisms.
Other types of protists include protozoa, which are single-celled, heterotrophic organisms that can move using cilia, flagella, or pseudopodia; slime molds, which are fungi-like organisms that can move and are often found in moist environments; and water molds, which are fungi-like organisms that can grow in water and can cause disease in plants and animals.

if 28% of the bases in a DNA strand are guanine, what percentage are thymine
Answer:
22%
Explanation:
According to Erwin Chargaff in his complementary base pairing rule, a DNA molecule consists of four nucleotide bases that pair with one another in the follow order: Adenine (A) to Thymine (T), and Guanine (G) to Cytosine (C).
According to Chargaff, the amount of Adenine in the DNA equals the amount of Thymine while the amount of Guanine in the DNA equals the amount of Cytosine. The sum of all the bases equals 100%. That is;
A + T + G + C = 100%
In this question, if 28% of the bases in a DNA strand are Guanine, the amount of Cytosine will also be 28%. Hence,
28% + 28% + A + T = 100
56% + A + T = 100
A + T = 100% - 56%
A + T = 44%
Since, A = T
A/T = 44/2
A/T = 22%
Hence, the amount of Thymine in the DNA strand will be 22%

A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper?
Answer:
[tex]\boxed {\boxed {\sf d=8.96 \ g/cm^3}}[/tex]
Explanation:
Density can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the copper is 89.6 grams.
The volume is 10 cubic centimeters.
[tex]m=89.6 \ g\\v= 10 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac{89.6 \ g }{10 \ cm^3}[/tex]
Divide.
[tex]d=8.96 \ g/cm^3[/tex]
The density of copper is 8.96 grams per cubic centimeter.
Which is an environmental factor that would MOST LIKELY have an adverse impact on the stability of an ecosystem?
The climate change would most likely exhibit an adverse influence on the stability of an ecosystem.
Climate change impacts on ecosystems:Climate change influences ecosystems in numerous ways. Warming may make the species to migrate to higher elevations or latitudes where temperatures are more favorable.
Climate change is resulting in the elevation of sea level, resulting in intrusion of seawater into the freshwater system, which is forcing the key species to relocate. Thus, removing the prey or predators, which are essential for the stability of the ecosystem.
Due to climate change, the vegetative biomes in the United States is predicted to change across 5 to 20 percent by 2100. A specific species due to climate change ca ripple through a food web and influence a broad array of other species, thus, disrupting the food web.
Change in climate and shift in ecological conditions could support the spread of parasites, pathogens, and diseases with potentially adverse influences on agriculture, human health, and fisheries. Climate change, along with pollution and habitat destruction is one of the stressors, which can result in the extinction of species.
Thus, climate change is the environmental factor, which would most likely exhibit an adverse influence on the stability of the ecosystem.

Blood has a lower concentration of hydrogen ions than cellular cytoplasm. What does that tell us about the pH?
Answer:Acids and bases In the human body, both blood and the cytosol (watery goo) inside of cells have pH values close to neutral. ... A base, in contrast, raises pH by providing hydroxide (OH −start superscript, minus, end superscript) or another ion or molecule that scoops up hydrogen ions and removes them from solution.

What term describes the strings of ribosomes that are attached to an RNA transcript at one time?
A. release factors
B. spliceosomes
C. transcription factors
D. mutagens
E. polyribosomes
Answer:
Polyribosomes.
Explanation:
During translation, the subunits of a ribosome surround the transcript and read down stream until they reach the start codon and begin polypeptide synthesis. Once the start codon is exposed, it is available for another ribosome to form around it, thereby initiating another locale for translation. Together the strings of ribosomes are called polyribosomes.

Explain how one celled organisms get oxygen in water.
Answer:
n unicellular organisms, oxygen diffuses across the cell membrane into the cell. Carbon dioxide diffuses out of the cell once the concentration of carbon dioxide is higher inside the cell than it is outside of the cell. Some micro-organisms, including some bacteria and fungi, can survive without oxygen.

Which sequence best explains the relationship between DNA and protein structure and function?
DNA → gene → protein → trait
DNA → amino acid triplets → protein → trait
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA shape → amino acid sequence → protein shape and function
ty <33
Answer:
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
Explanation:
From Google:
"The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides [base triplet] in the gene (DNA) encoding it."

A line passes through the points( -3,-4) and (6,2)
Answer:
y = ⅔x - 2
Explanation:
We can solve for a linear equation of a line that passes through these two points by the elimination method and then substitute.
We simply write these two points in the form y = mx + c, where m is the gradient and c is the y-intercept (offset). So:
-4 = -3m + c
2 = 6m + c
____________ -
We can first eliminate c to solve for m and then substitute m back into either equation to solve for c. (See attached image for solving steps)
Then, we get:
m = ⅔
c = -2
so y = ⅔x - 2

Gregor Mendel conducted thousands of genetic experiments using pea plants. Mendel is called the Father of Genetics because it was these studies that lead to the principles of genetics. In one of his many experiments, he crossed purple-flowered pea plants with white-flowered pea plants. Much to his surprise, all of the offspring turned out to be peas with purple flowers in appearance.
Although Mendel used the term factors instead of genes, how did Mendel explain why all the pea plants had purple flowers and not a mixture of white and purple flowers?
A.The offspring received the factors (genes) from both parents, but the genotype for purple flowers dominated over white flower pea plants.
B.The offspring only received the factors (genes) from the parent with the genotype for purple flowers and nothing from the white flower parent.
C.The offspring received the factors (genes) from both parents, but the phenotype for purple flowers dominated over the factor for white flowers.
D. The offspring only received the factors (genes) from the parent with the phenotype for purple flowers and nothing from the white flower parent.
Answer:
A
Explanation:
The purple gene was dominant, so though the plants got "factors" from both parents, only the purple gene was expressed in their phenotype (purple petals).
