3. Which parts are located within the chloroplast? (Select all that apply.)
stroma
granum
xylem
phloem
Explanation:
As I think Stroma and granum are the correct answer.
There are two distinct regions present inside a chloroplast known as the grana and stroma. Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.
What are Gametes cells?
Answer:
I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.
Hope it help you!:)
Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

_______ 9. A severe mutation may lead to cell death and may have no effect on the body.
_______ 10. Most mutation are harmful.
Answer:
FalseFalseFalseFalseTrueTrueFalseTrueTrueFalseExplanation:
_False_1. A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleic acid.
Nucleotides: subunits or monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base. The chain or sequence of nucleotides composes the polymer. Different nucleotides joined by their extremes compose the nucleic acid: DNA or RNA.
A molecular group consisting of a sugar molecule, a phosphate group, and a nitrogenous base is a nucleotide.
_False_ 2. In a DNA molecule, a base pair would be composed of adenine and guanine.
In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. A-T pair is united by 2 hydrogen bonds, and the G-C pair is united by 3 hydrogen bonds.
In a DNA molecule, a base pair would be composed of adenine and timine, or In a DNA molecule, a base pair would be composed of cytosine and guanine.
_False_ 3. Cytosine and adenine are purines.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
Guanine and adenine are purines.
_False_ 4. During the replication of DNA, bonds are broken between the phosphate groups.
During the replication of DNA, bonds are broken between the hydrogen groups.
_True_ 5. RNA contains the nitrogenous base uracil.
Instead of Timine, RNA contains uracil that pairs with adenine.
_True_ 6. There are 20 different amino acids in a cell.
_False_ 7. The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts.
When mRNA leaves the nucleus, meets a free ribosome in the cytosol. Into this organelle, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.
The coded message carried by messenger RNA is translated into polypeptides at organelles called ribosomes.
__True__ 8. The decoding of a messenger RNA message into a polypeptide chain is known as translation
__True__ 9. A severe mutation may lead to cell death and may have no effect on the body.
_False_ 10. Most mutation are harmful.
A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but most of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection, leading to evolution.
Most mutation are not harmful
Based on structure, DNA molecules are composed of nucleotides and mutations in DNA are mostly harmful.
What is DNA?DNA refers to sequences of nucleotides which contain the genetic information of organisms.
Nucleic acids are chains of nucleotides.
Nucleotides are molecular group consisting of a sugar molecule, a phosphate group and a nitrogenous base.
Four nucleotides are present in DNA and they include:
adenine guanimecytidine andthymidineIn a DNA molecule, a base pair would be composed of adenine and guanine is false because adenine bonds to thymine, while guanine bonds to cytidine
Cytosine and adenine are purines is false because cytosine is pyrimidine while adenine is a purine
During the replication of DNA, bonds are broken between the phosphate groups is false because the bonds broken are hydrogen bonds.
RNA contains the nitrogenous base uracil is true as uracil is found in RNA in place of thymine in DNA.
There are 20 different amino acids in a cell is true as these amino acids are found in proteins.
The coded message carried by messenger RNA is translated into polypeptides at organelles called chloroplasts is false because protein synthesis occurs at the ribosomes.
The decoding of a messenger RNA message into a polypeptide chain is known as translation is true.
A severe mutation may lead to cell death and may have no effect on the body is false because mutations can cause death of organisms.
Most mutation are harmful is true because only free mutations are beneficial.

Mushrooms and yeasts reproduce by spores and are composed of cells enclosed by cell walls. These organisms fall into which kingdom?
Answer:
Fungi kingdom.
Explanation:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.
The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.
Kingdoms include different phyla closely related.
The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

Answer:
presence of the placenta (mammals)
Explanation:
Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.
What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?
Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.

What is one effect the hydrosphere has on the lithosphere 1).Erosion of rocks 2).Evaporation of water 3).Heating of the core 4).Melting of the core
Answer:
1).Erosion of rocks
Explanation:
Erosion of rocks has effect of hydrosphere on the lithosphere. When the river and streams passing through a region, the water eroded the rocks that comes in their way with the passage of time as well as the bank of the rivers. The speed of erosion depends on the speed of the flow of rivers because speedy flow of rivers causes fast erosion of rocks so we can say that the erosion is the main effect of hydrosphere on the lithosphere.
Which statement best describes the motion of the plates along these boundaries that causes the earthquakes? The plates push apart from each other with no subduction. Subduction occurs with the less-dense plate sinking below the other plate. Subduction occurs with the more-dense plate sinking below the other plate. The plates smash together with no subduction.
Answer:
D). The plates smash together with no subduction.
Explanation:
As per the question, the last statement most adequately demonstrates the movement of plates i.e. 'the plates hit together without any detraction' through concurring boundaries causing the earthquakes to take place. The continuous smashing of tectonic plates with one another leads to the development of a pressure towards both the rock layers by the time this stress is released through a shaky or convulsive movement of the Earth. Thus, option D is the correct answer.
Which pattem of wind flow is most likely to occur during a hot summer season in a coastal location?
А
From land to sea, toward areas of lower air pressure.
B.
From sea to land, toward areas of lower air pressure
С
From land to sea, toward areas of higher air pressure.
D
From sea to land, toward areas of higher air pressure
Answer:
B. From sea to land, toward areas of lower air pressure
Explanation:
The pattern of wind flow is most likely to occur from sea to land during a hot summer season in a coastal location due to difference of air pressure. In the summer season when the land is heated, the temperature of the air also increases and hot air rises up, as a result a region of low pressure is created at the surface. The air over the sea moves into this area of low pressure on the land. Hence, the direction of the wind is from the sea to the land during the day in summer season.

_________ is when the cell uses the mRNA code to build protein. This process takes place in the _________ with the help of the organelle called the ___________.
Answer:
1. Translation
2. Cytoplasm
3. Ribosome
Explanation:
Translation is a process whereby the cell uses a mRNA template to produce an amino acid sequence (protein). It is the second stage of gene expression in living organisms.
Translation occurs in the CYTOPLASM of a cell with the help of an organelle called RIBOSOME. The ribosome attaches to the mRNA molecule in the cytoplasm to initiate the process of translation.
