dexar [7]3 years ago
4 0

Answer:

(look at the explanation below)

Explanation:

A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages.

Which molecules is the primary product of photosystem i?
Lady bird [3.3K]

Answer:

NADPH

Explanation:

Photosystem is the complex structure formed by the chlorophyll molecule proteins and other light-harvesting pigments. There is two types of photosystem present in the plants: PSI and PSII.

The PSI system absorbs 700 nm wavelength of light and energises the electron coming from the PSII. This electron is then passed on to Ferredoxin to NADP reductase which converts the NADP to NADPH.

Since NADPH is formed after the electron is energized from PSI, therefore, NADPH is the correct answer.

reduced electron carrier NADPH.

The high-energy electron travels down a short second leg of the electron transport chain. At the end of the chain, the electron is passed to NADP^+  

+

start superscript, plus, end superscript (along with a second electron from the same pathway) to make NADPH.

Differentiate between Mesozoic era and Cenozoic era on the basis of time scale and origin of species.​
Mama L [17]

Answer:

Explanation:

The Mesozoic Era is known as period of significant tectonicas well as climate, and evolutionary activity. It was known as as " Age of Dinosaurs or Reptiles" . During this era, the dominant form of life is dinosaurs.The Mesozoic Era come to life, arround 252.2 million years back. This Era can be sectioned into three different periods which are; ✓Triassic

✓Jurassic

✓Cretaceous

The span period of Cenozoic era was about 65 million years, this range from the end of the Cretaceous Period as well as the extinction of non-avian dinosaurs up to the present. Cenozoic era can be reffered to Age of Mammals such as (woolly rhinoceroses) this is because the largest land animals at this is mammals .The Cenozoic Era can be regarded as "new life" and it's known to be " age of mammals simply because largest animal that is available that time is mammals This era serves as the current as well most recent era among the three geological eras of the Phanerozoic Eon. The Cenozoic era has its spans of about 65 million years, and this range from towards end of the Cretaceous Period to the extinction of non-avian dinosaurs up to the present

The Cenozoic Era can be sectioned

into three periods which are;

✓ Paleogene : This is arround 66 million to 23 million years ago)

✓ Neogene : This is arround 23 million to 2.6 million years ago)

✓Quaternary; This is arround 2.6 million years ago to the present);

Alleles A and a are located on a pair of metacentric chromosomes. Alleles B and b are located on a pair of acrocentric chromosom
Leto [7]

Answer:

See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome

Explanation:

According to the position of the centromere, chromosomes can be of 4 types namely:

  1. Metacentric
  2. Acrocentric
  3. Telocentric
  4. Sub-metacentric

A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.

Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.

Telocentric chromosomes have their centromeres at one end of the chromosome.

Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.

The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
