Two aligned sequences fo the same gene differ by four substitutions, all transitions, two more sequences for the same gene also

differ by found substitutions, two transitions and two transversals. which pair of sequences has probably been evolving independently longer and how do you know?
Biology
1 answer:
Ganezh [65]3 years ago
5 0

Answer:

The first pair of sequence.

This is because transitions are interchangeable of two ringed purines A to G or of one ringed pyrimidine C to T they therefore involves bases of similar shapes.

Transition mutations are generated at higher frequency than transformation which is interchangeable of purines for pyrimidine bases which involves exchange of one ring and two ring structures.

How do sediment deposits affect waterwats
makvit [3.9K]
<span>The deposition of heavy sediment can significantly diminish the water quality and aquatic habitat.  The sentiment in the water can reduce the sunlight that reaches the floor of the waterway, affecting animal and plant life. For example, photosynthesis may be less effective due to the decreased sunlight and the gills of fish may get clogged from the sediment.</span>

Art [367]

Answer:

The options have been placed in the comment section. The answer is C. Inheritance of genes from both parents

Explanation:

Gregor Mendel is referred to as the FATHER OF GENETICS due to his immense contribution to the discovery of how traits are passed down or inherited from parents to offsprings. He found out that a unit of inheritance, which was later called GENE, was responsible for each individual trait of pea plants.

In his numerous experiments, Mendel discovered that the characteristics/traits of pea plants were determined by the contribution of both parents. Mendel hypothesized that each parent contributed 50% of this unit of inheritance via fertilization to the characteristics of an offspring. Hence, the inheritance of genes from both parents determines the characteristics of a pea plant.

Which group of macromolecules includes triglycerides waxes and cholesterol?
Mkey [24]

Answer:

Carbohydrates, Nucleic acids, Proteins, and Lipids

A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1.

Nucleic acids are bio-polymers, or large bio-molecules, essential for all known forms of life.

Proteins are large bio-molecules, or macro-molecules, consisting of one or more long chains of amino acid residues.

In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.

Neurons and muscle cells perform different functions. In the body, these cells have the sar
n200080 [17]

The central nervous system (CNS) and effector organs receive messages from receptors through the nerve cells, respectively.

<h3>What do neuron and muscle cells have in common?</h3>
  • Tissues are made up of both nerve and muscle cells. Both mitochondria and endoplasmic reticulum are found in muscle and nerve cells. The body's operations are coordinated through the cooperation of muscle and nerve cells.
  • Neurons, a type of nerve cell, and muscle cells are significantly distinct from one another. While nerve cells transmit signals from receptor cells to either glandular cells or muscle cells, or both, in order to move the body, muscle cells (myocytes) contract to cause movement.
  • The synapse is the point at which a nerve cell can communicate with another cell or muscle cell. The space between the pre-and postsynaptic cell membranes is known as the synaptic cleft.

The function of muscle cells:

The same genetic material can be used to correctly fill in the first blank, and to contract can be used to correctly fill in the second blank.

The genetic material is present in all of the body's cells, including blood, muscle, neuron, and cardiac cells. Cell differentiation causes them to specialize into different types of cells.

Muscle cells' purpose is to contract, which aids in movement and mobility. Skeletal muscles aid in movement and smooth muscles support the operation of interior organs like the uterus, whose contractions aid in childbirth.

The central nervous system (CNS) and effector organs receive messages from receptors through the nerve cells, respectively.
