Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes.
Answer:
The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.
Explanation:
The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.
All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.
The question is incomplete as it does not have the options which are provided in the attached picture.
Answer:
Option-B
Explanation:
The theory of the endosymbiotic origin of eukaryotes proposed that the organelles like the chloroplast and mitochondria are originated when the proto-eukaryotes engulfed the prokaryotic cells.
The chloroplast was formed in some eukaryotes instead of others as the proto eukaryotes diverged into many lineages before the origin of the chloroplast in them. One of the lineages engulfed the chloroplast and become photosynthetic organism but rest of the proto eukaryotic lineage did no engulfed the bacteria and did not possess the chloroplast.
Thus, Option-B is the correct answer.
Answer: 3.88889 degrees Celsius
Explanation: 3.88889 degrees Celsius
A
Carbon can form compounds of many sizes and shapes.
B
Animals need carbon in order to breathe.
C
Plants use carbon to absorb water into their roots.
D
Carbon is the most abundant element on Earth.
The correct answer A
This is in part due to carbon's ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life
Answer:
D
Explanation:
Our DNA, RNA, proteins, and something else I forget are all made of carbon. As a result, carbon is essentially one of the reasons we exist. Carbon can form connections with other atoms as well. Carbon makes up the majority of organisms.
I'm sorry if this is wrong
Recombination reshuffles alleles of two genes that lie on the same chromosome type, whereas independent assortment reshuffles alleles of two genes that lie on different chromosome types.
Explanation:
Alleles are two forms of same gene, they are located on the same loci of the homologous pair.
Recombination occurs when alleles from two homologous chromosomes get reshuffled during crossing over in meiosis.
Independent assortment refers to the tendency of alleles to be inherited independently from one generation to other.
