What would happen to a plant if the chloroplasts in its cells became damaged?
(1 point)
O The plant would be unable to make protein.
O The plant would be unable to reproduce.
O The plant would not have a rigid structure.
O The plant would not make glucose and oxygen.
Answers
If the chloroplasts of the plant cell become damaged, it would not be able to make glucose and oxygen. So the correct option is D.
What are chloroplasts?Photosynthesis, the mechanism by which light energy is transformed to chemical energy and results in the generation of oxygenation and energy-rich organic molecules, takes place in the chloroplast, a structure found inside the cells of green algae and plants.
Endosymbiotic hypothesis holds that mitochondria and chloroplasts, which are energy-producing structures in eukaryotic cells, are descended from photosynthetic cyanobacteria, which are free-living near cousins of chloroplasts.
A plastid is a sort of body that is formed like a disc, an oval, or a circle and is used to synthesise and store food. Chloroplasts are one type of plastid. The green colour of chloroplasts, which derives from the existence of two pigments called chlorophyll a and chlorophyll b, sets them apart from other plastid types.
These pigments have the capacity to absorb light energy for the purpose of photosynthesis. Carotenoids are one of the additional pigments found in chloroplasts that act as accessory pigments, capturing sun energy and transferring it to chlorophyll.
Therefore the correct option is D.

1.)If ang 1-7 and ACEII levels are increased it will result in heart failure-Angiotensin converting enzyme 2 (ACE2), a homologue of ACE, is a monocarboxypeptidase that converts angiotensin II (Ang II) into angiotensin 1–7 (Ang 1–7) which, by virtue of its actions on the Mas receptor, opposes the molecular and cellular effects of Ang II. ACE2 is widely expressed in cardiomyocytes, cardiofibroblasts, and coronary endothelial cells.
2.) ACE2 and ang 1-7 is thought to be cardio protective because ACE2 and Ang 1–7 have emerged as a key protective pathway against heart failure with reduced and preserved ejection fraction
3.) three strains of coronavirus: SARS-CoV, NL63 and SARS-CoV-2. ACE2 receptors are ubiquitous and widely expressed in the heart, vessels, gut, lung - so yes it would increase the likelihood of being infected
An organelle found in most eukaryotic cells described as "cellular power plant"
Answers
Answer:
[tex]\boxed {\boxed {\sf Mitochondria}}[/tex]
Explanation:
The mitochondria is commonly called the powerhouse of the cell.
This is because it is the organelle that makes energy for the cell. The process of cellular respiration occurs in the mitochondria.
Cellular respiration turns glucose from food and oxygen into carbon dioxide, water, and ATP. ATP is useable energy for the cell, its metabolism, and its processes.
Mitochondria are found in eukaryotic cells, because it is a membrane bound organelle.
So, the organelle this question describes is the mitochondria.

Explain your thinking. Describe how variations are passed on from one generation to the next.
Answers
Through gene rearrangement, genetic variation occurs from generation to generation.
What is genetic variation?
Only genetic variation—not environmental variation—can be passed on to the next generation. If two populations of the same species' phenotypes diverge to the extent that they are unable to mate and produce fruitful offspring, they may split into two separate species.
Genetic variations can result from gene variants, commonly referred to as mutations, or they can arise naturally when a cell divides, when its genetic material is naturally rearranged. Genetic alterations that alter gene activity or protein function can create many phenotypes into an organism.

Answers
Answer:
They can grow into any type of body cell.
Explanation:
Stem cells are immature cell types- they are somatic cells, that contain the entire genome of an organism. The genome is made up of DNA, which encodes instructions for the cell.
These may potentially become various other types of cells through the process of differentiation and reach maturity. In differentiation, chemical signalling, and gene expression ultimately determine the cell's fate.
Four random genetic matches then formed the following diploid offspring. Using the text box or pen tools, label the alleles on each offspring.
Answers
Crossing-over events occur during the prophase 1. After anaphase 2, telophase 2, and citokynesis, 4 gametes are formed. Each gamete has different genetic information. Alleles are labeled in the attached file.
--------------------
Since I do not have the parentals genotype, I will consider two traits, each coded by a single diallelic gene.
Gene 1:
A is the dominant allelea is the recessive alleleLocated in the superior arm of the chromosomeGene 2:
B is the dominant alleleb is the recessive alleleLocated in the inferior arm of the chromosomeI will assume that both parents are heter0zyg0us for both traits, so their genotypes are AaBb.
During gamete formation, the pairs of h0m0logous chromosomes separate after crossing over. Then, sister chromatids also separate. The result is the formation of four gametes.
Each gamete has different information from the combination of h0m0logous chromosomes belonging to the father and to the mother.
Mother
During the prophase of meiosis 1, the mother's homologous chromosomes express two crossing-over events. One of them in the superior arm and the other one in the inferior arm.
The segments interchange between chromosomes involves Gene 1 and Gene 2.
During anaphase 2, sister chromatids separate, and after telophase and cytokinesis, four haploid gametes are formed carrying the following chromosomes,
AB → Parentalab → RecombinantAB → Recombinantab → ParentalFather
During the prophase of meiosis 1, the father's homologous chromosomes express one crossing-over event in the inferior arm.
The segments interchange between chromosomes involves Gene 2.
During anaphase 2, sister chromatids separate, and after telophase and cytokinesis, four haploid gametes are formed carrying the following chromosomes,
AB → ParentalAb → RecombinantaB → Recombinantab → ParentalGametes' destiny is to randomly merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization.
The zygote is a complete cell that suffers successive mitosis to form the new organism.
In the exposed example,
Offspring 1 → Parental gamete ab from the mother merged recombinant
gamete aB from the father → genotype aaBb
Offspring 2 → Parental gamete AB from the mother merged recombinant
gamete aB from the father → genotype AaBB
Offspring 3 → Recombinant gamete ab from the mother merged
recombinant gamete Ab from the father → genotype Aabb
Offspring 4 → Parental gamete ab from the mother merged recombinant
gamete ab from the father → genotype aabb

Answers
Answer:
A
Explanation:
The structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.
What were the first plants to live on land?The first plants that were tends to live on land are the Non-vascular plants, which include mosses and liverworts, which were the first-ever land plants. They do not have much of an internal support system but have slightly simpler material for the same tasks.
Early in their history, land plants also evolved a cuticle. The cuticle is the structure that involves a waxy layer on the outer surface of the aerial parts of a plant that helps to prevent water loss. Sometimes cuticle with details of epidermal cell structure is preserved in fossil plants.
Guard cells play an important role in the opening and closing of the stomata. While epidermis is the outer cell which prevent the whole plant form injury.
