Which one of the following was not described as part of the eukaryotic endomembrane system?

Primary growth or lengthening of plants results from mitotic division in cells of which tissue?

Lesechka [4]

Primary growth or lengthening of plants results from mitotic division in cells of the apical meristem tissue. The apical meristem can be found in the top of plants. When the plant divides, it helps to lengthen it. The correct choice is C.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

The DNA sequences may vary but the amino acid sequences are identical.
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the genetic information contained in the DNA varies from one species to another, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur

Shtirlitz [24]

Answer and Explanation:

$Greetings!$

$Let's~answer~your~question!$

Q1. Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur normally. Consider how the absence of crossing over would affect the outcome of meiosis.

→ $There~ would ~be~ less~ genetic ~variation~ among ~gametes.$

$Thus,~making~statement~``e"~correct!$
