Under a microscope, a student observes a specimen containing a cell wall, nucleus, and chloroplasts.
Which of the following could the specimen being observed belong to?
Answer:
A plant cell b/c it has chloroplast
Explanation:
Chloroplast absorbs sunlight also known as light energy used for the process of photosynthesis.
The observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.
PLANT CELL:
A plant is an organism whose cells contain organelles called chloroplast, which harbors chlorophyll pigment. This feature enables them perform photosynthesis; a process that plants use to synthesize their food.Plant cells are eukaryotic in nature i.e. they contain a membrane-bound nucleus in their cells. In addition to these organelles, plant cells also possess a cellulose-embedded cell wall that strengthens the cell. Therefore, the observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.Learn more at: https://brainly.com/question/1894299?referrer=searchResults
Matthias Schleiden used a microscope to observe that the
parts of plants consist of cells. Theodor Schwann used a
microscope to observe that the parts of animals consist of
cells.
Which two statements did the work of Schleiden and Schwann add to the cell
theory?
A. All living things are made of one or more cells.
B. All cells come from other living cells.
C. Cells contain genetic material that consists of DNA.
D. The cell is the basic structural and functional unit of life.
Answer:
The work of Schleiden and Schwann provided to the Cell Theory the conclusions relating to that all living things are made of one or more cells and the cell is the basic structural and functional unit of life.
Explanation:
Matthias Schleiden was a German botanist who in 1937, while studying plant tissue under the microscope, observed that all plants are made up of cells.
In 1938, physiologist Theodor Schwann performed an experiment similar to Schleiden's, but using animal tissue, concluding that animals are made up of cells.
By bringing together the findings of both scientists, two important conclusions for Cell Theory were reached:
The cell is the structural and functional unit of all living beings. All living organisms are made up of one or more cells.Both conclusions are part of the cellular theory, as it is known today.
Regarding other options:
B. All cells come from other living cells was a conclusion provided by Rudolf Virchow.
C. Cells contain genetic material that consists of DNA is an argument that is not part of the cellular theory. In fact, the DNA would not be discovered until 1953.

Explanation:
The first answer would be most correct, but you might also be able to draw the conclusion that there are more unhealthy people than healthy people.
Answer:
1st one
Explanation:
I believe that you can assume the 1st one, but you can't really assume that they have more unhealthy people than healthy. You don't have any numbers to prove that.

Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.
Answer:
C. Electromagnetic energy is transformed into chemical energy
Explanation:
Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.
This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.
it is C. Electromagnetic energy is transformed into chemical energy.
Wich cellular process takes place in the ribosomes that are bound to the endoplasmic reticulum? a.- the breakdown of waster material b.- the conversion of radiant energy to glucose c.- the synthesis of new proteins d.- the replication of nucleic acids.
Answer:
C
Explanation:
Ribosomes are organelles which produce protein inside a cell. They do the same even if they are on an ER membrane.
Hope this helps! :)
Answer:
C
Explanation:
Here, we want to select the answer that best answer the question out of the options.
The correct answer in this case is that these ribosomes are present for the sole purpose of protein synthesis.

What are plasmids?
A. Enzymes that bond genetic materials together
B.small rings of bacterial DNA
C. Enzymes that cut DNA
D. Simple organisms with only one chromosomes
Answer:
b. small rings of bacterial DNA
Answer:
B
Explanation:
The plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.

Explanation:
Once amylase has broken down starch, can it break down another starch molecule?
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

7. What happens during mitosis?
(a) The nucleus of the cell divides.
(b) The cytoplasm of the cell divides.
(c) The cell divides.
(d) The DNA replicates.
Answer:
(c) The cell divides.
Mitosis is the process in which a cell divides.
Mitosis is one of the two types of cell division. The other type of cell division is Meiosis.
Meiosis takes place in reproductive cells and the cell is divided into two which is further divided into four by Meiosis-II
While in Mitosis the process is somewhat similar, the parent cell divides into two new cells and there is no further division and also the parent cell and the two daughter cell will be the exact same
The primary source of energy for most organisms are
Answer: The Sun
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

When a trait is shown and at least one letter is upper case.
A) dominant
B) recessive
C) trait
D) allele
Answer:
maybe trait?
Explanation:
dunno lol
Answer:
When a trait is shown and at least one letter is upper case, it is a dominant allele (option A).
Explanation:
In genetics the presence of a dominant allele - represented by a capital letter - is sufficient to suppress a recessive allele, expressing the dominant trait in the phenotype.
Dominance is based on allelic combinations of the genotype, which are expressed in the phenotype for a given characteristic:
Two dominant alleles (AA) express the only possible trait, dominant.One dominant allele and one recessive allele (Aa) show a dominant phenotype, as the former suppresses the latter. It is a hybrid or heterozygous.Two recessive alleles (aa) show a phenotype with the recessive trait.The other options are not correct, because:
B) Recessive is the allele that is only expressed in the phenotype when there is a pair in the gene.
C) Trait is equivalent to a characteristic.
D) Allele represents the different ways in which a gene is expressed.

Which way do monsoon winds blow during the summer months?
O toward the land
O counterclockwise
O clockwise
O toward the sea
5 6
7
During the summer the wind blows from the south west so it will blow toward the land.
What is summer?One of the four seasons is summer. The summer months are the warmest of the year. Summer can be the wettest (and rainiest) season in some regions while being a dry season in others.
In regions that are neither too hot nor too cold, there are four distinct seasons. Summer arrives on Earth's north and south poles at diametrically opposed times of the year.
Summer occurs between the months of June and September in the northern hemisphere and between December and March in the southern hemisphere. This is because the south of the Earth always faces away from the Sun while the north always faces the Sun.
Therefore, During the summer the wind blows from the south west so it will blow toward the land.
