The correct answer is C4 plants.

A plant that cycles carbon dioxide into four-carbon sugar components to get into the Calvin cycle is known as a C4 plant. These plants are very effective in dry, hot climates and produce ample energy. Various foods one consumes are C4 plants like pineapple, corn, and sugar cane.

In the C4 plants, at the start carbon fixation occurs in the mesophyll cells and the Calvin cycle occurs in the bundle-sheath cells. The PEP carboxylase combines with an incoming molecule of carbon dioxide to the three carbon-molecule PEP, generating a four carbon molecule, that is, oxaloacetate.

Which of the following correctly describes how nerve impulses move throughout the body?

ikadub [295]

The correct options are as follows:
1. ELECTRICAL TRANSMISSION THROUGH NEURONS AND CHEMICAL TRANSMISSION BETWEEN NEURONS [D].
Neurons, which are the nerve cells that carry nerve impulses are made up of cell body and dendrites. Electrical events propagate signals within a neuron and chemical processes transmit the signals from one neuron to the other.
2. SENSORY NEURON - BRAIN - SPINAL CORD - MOTOR NEURONS [B].
Waking up from sleep involves sensory neurons. Hearing of a strange sound is made possible by the activity of the brain. The man become alarm as a result of the message to the body from the brain via the spinal cord and running involves motor neurons.
3. MOTOR NEURONS AND SENSORY NEURONS [A].
The peripheral nervous system is one of the two components of the nervous system and is made up of the nerves and the ganglia outside the brain and the spinal cord. The neurons of the peripheral nervous system is made up of sensory and motor neurons. The sensory neurons bring signals to the central nervous system while the motor neurons carry signals out of the central nervous system.

Identify the start and stop codons in the mrna sequence 5'-uauccauggcacuuuaaac-3'. what is the resulting amino acid sequence

sladkih [1.3K]

MRNA is read 5->3
Start codons can vary depending on the cell/organism type although more generally for mRNA it is always: AUG which is always Methionine

Stop codons for mRNA are:
UAG ("amber") , UAA ("ochre"), UGA ("opal")


5'-uaucc.aug.gca.cuu.uaa.ac-3'

M-A-L
Methionine-Alanine-Leucine

Answer:

Option 1 : prokaryotic cells

Explanation:

Notably, prokaryotic cells lack a nucleus and membranous organelles. Prokaryotic cells have the following features: 1. The genetic material (DNA) is localized to a region called the nucleoid which has no surrounding membrane.

What is the principle of common descent?

Marat540 [252]

The theory of common descent states that all living organisms are descendants of a single ancestor. Phylogenetic trees and cladograms are often used to hypothesize the evolution of various organisms and shared common descent.

Hope that helped you:)
