Once researchers identified DNA as the unit of inheritance, they asked how information was transferred from the DNA in the nucle

us to the site of protein synthesis in the cytoplasm. What is the mechanism of information transfer in eukaryotes?A. DNA from a single gene is transcribed to mRNA and transported to the cytoplasm, where mRNA serves as an information carrier for protein synthesis.B.Transfer RNA takes information from DNA directly to a ribosome, where protein synthesis takes place.C.Proteins transfer information from the nucleus to the ribosome, where protein synthesis takes place.D.Messenger RNA is transcribed from a protein and transfers information from the nucleic acids in the cytoplam to the nucleus where protein synthesis takes place.

Answer:

The answer is A.

Explanation:

From DNA inside the nucleus , the messenger RNAs is synthesized and the mRNA is given to cytoplasm. This mRNA will lead to ribosome which protein synthesis occurs. Due to sequence in mRNA, the tRNA collect the needed aminoacid and synthesize the protein by collecting amino acid from cytoplasm due to codons in mRNA.

Which of the following strands is the correct complement to the strand ATC-GTC-CCA
Basile [38]

Answer: The correct complementary DNA sequence for the given sequence is D. TAG-CAG-GGT.

DNA contains nucleotide pairs on a sugar phosphate backbone. The nucleotide pairs are connected by hydrogen bonds and each nucleotide pairs with only one other nucleotide. The bases are of two types: purine and pyrimidine. The purine bases bond only to pyrimidine bases. The base pairing follows Chargaff’s rule where adenine forms a pair with thymine by two hydrogen bonds and Guanine forms a bond with cytosine with three hydrogen bonds between them.

Alexandra is researching the effects plate tectonics have on the shape of Earth. Which of the following is a result of plate tec
zloy xaker [14]

D)Heat within Earth

Explanation:

The heat from within the earth is as a result of plate tectonics. Plates on the earth are driven by heat within the earth through convection currents.

  • Plate tectonics suggests that the earth are broken into slabs that moves on the weak and ductile material called asthenosphere.
  • Heat from within the earth causes the melting of asthenosphere.
  • The riding lithosphere which is cold will sink into the asthenoshpere.
  • Hot mantle materials will move to the surface thereby setting up a convection current.
  • Heat from within the earth rises to the surface due to plate movement.

Match the following:Part A1. Transverse foramina present.2. No canals or foramen present. It articulates superiorly with the sac
Stels [109]

Answer:

1. Transverse foramina present: Cervical

2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx

3. Receive the most stress: Lumbar

4. Attach to ribs: Thoracic

5. Articulates with hip bones of the pelvis: Sacrum

Explanation:

The vertebral column is a <u>series of 33 bones called vertebrae</u> that play a key role in organ protection, movement of body, and overall support. The column has been divided into <u>5 different regions</u> with the number of bones.

<u><em>1. Cervical Vertebrate</em></u><u>:</u> These are the group of <u>seven vertebrae of the neck</u>, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head.  They have <u>transverse foramina</u> which <u>gives passage to vertebral artery and vein</u>.

<em><u>2. Thoracic Vertebrae:</u></em> They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.

<em><u>3. Lumbar Vertebrae: </u></em>This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They <u>carry all of the upper body weight</u> providing flexibility and movement to the trunk region.  This is why it can <u>receive the most stress easily</u>.

<em><u>4. Sacrum Vertebrae: </u></em>There are 5 sacral vertebral fused bones. It <u>connects to the hip bones and play role in forming a strong pelvis</u>.

<em><u>5. coccyx Vertebrae:</u></em> These are a group of 4 fused bone. There is <u>no vertebral canal due to a lack of vertebral arches</u>. They <u>provide </u>an <u>attachment site for muscles</u> ligament and tendons. They also <u>play a role in stabilization and support</u> while sitting.

Using the table on the right as a guide, answer the following questions about light-independent reactions.
Eddi Din [679]

The products of light-independent reactions include the following:

  • Glucose
  • NADP+
  • Water (H₂O).

<h3>What is photosynthesis?</h3>

Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs) convert light energy (sunlight) received from the Sun into chemical energy, in order to enable them make their food.

<h3>The stages of photosynthesis.</h3>

In Science, there are (2) main reactions that make up the process of photosynthesis and these include following:

  1. Light-dependent reactions.
  2. Light-independent reactions.

<h3>What are light independent reactions?</h3>

Light independent reactions can be defined as a type of photosynthetic reaction that occurs in the stroma of the chloroplasts and it requires the following necessary inputs:

  • Carbon dioxide
  • Adenosine triphosphate (ATP)
  • NADPH

Additionally, NADPH, adenosine triphosphate (ATP), and oxygen are the outputs (end products) of photosynthesis.

In this context, we can reasonably infer and logically deduce that glucose, water (H₂O), and NADP+ constitute the products of every light independent reactions.
