Answer:
In pigs, this gene suffered duplication and then paralogous genes diverged by accumulating mutations during evolution
Explanation:
Paralogous genes can be defined as evolutionarily related genes that emerged by duplication in a common ancestor of the two species being compared. Gene duplication is one of the most important mechanisms of genome evolution by which paralogous genes arise and acquire novel functions. After gene duplication, one of the two functional gene copies is prone to accumulate mutations because the organism has two genetic sequences to produce the same protein encoded by this gene. In consequence, it is expected that the cDNAs obtained from these genetic sequences show differences in nucleotide length.

(2.) all undergo external development
(3.) may have evolved from a common ancestor
(4.) have adaptations for the same environment as adults
Answer:
Yeah it is considered as a same species
The diagram to the right represents stages in the embryonic development of four organisms. The diagram shows that all members of the same species. The correct option is 1.
What is an embryo?An embryo is a term given to an unborn baby. It is the living form that is present inside the womb of a woman. This is the developing stage of a baby. There are different stages of development in different species, and their terms are also different.
Embryonic development is the stage where the baby develops inside the womb or an egg to fully developed to come out to the outer environment. Here, the embryonic stages are of the same species. As the diagram shows the development, there are very many similarities.
Thus, the correct option is 1. All members of the same species.

1. A common misconception is that plants perform photosynthesis INSTEAD of cellular
respiration. This is incorrect because plants carry out BOTH photosynthesis AND
Cellular respiration
Explain why plants need to use both process in order to survive,
Answer:
Please find the explanation below
Explanation:
Photosynthesis is the process whereby plant cells manufacture their energy source or food (glucose) in the presence of sunlight. Cellular respiration, on the other hand, is the process by which living cells release energy in form of ATP needed by their cells for cellular activities.
Living organisms eat or obtain take in food in order to obtain energy for their cellular upkeep. Plants are one of the only set of organisms that can produce their own food i.e. autotrophic and they do so via PHOTOSYNTHESIS. However, they need to undergo cellular respiration in order to breakdown the synthesized food to yield usable energy for their cells. These two processes in plants are direct metabolic opposite of one another.
Based on the explanation above, plants need to use both PHOTOSYNTHESIS AND CELLULAR RESPIRATION because the products of one yields reactant for the other. photosynthesis uses carbon dioxide released by cellular respiration while cellular respiration uses oxygen released by photosynthesis.
Which is NOT a function of the stem in plants?
O Store water
O Carry nutrients
O Provide support to the plant
O Anchor the plant in the ground
Answer:
yes D is the answer
Explanation:
cuz steam store water carry nutrients and of course provide support to the plant
Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.
What are stems?Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.
The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.
The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.
Therefore, option D. anchor to the ground is not provided by the stem.

I got to compare a plant and animal cell! the plant cells are similar to brick walls. nice and organized! while animal cells were... messy.

What receives nerve impulses?
A. Cell body
B. Dendrites
C. Axon
D. Myelin sheath
Explanation:
Dendrites receive nerve impulses from other cells.
Hope it help..The right answer is B. Dendrites receive nerve impulses.
What are Dendrites ?Dendrites are specialized structures on neurons that receive signals, or impulses, from other neurons or from sensory receptors in the environment. These signals can be either electrical or chemical, and they are transmitted across synapses, which are tiny gaps between neurons or between neurons and effector cells, such as muscles or glands.
Dendrites play a crucial role in the transmission and processing of these signals. They are covered in tiny protrusions called dendritic spines, which increase the surface area of the dendrite and allow for a greater number of synapses to be formed with other neurons. This increased connectivity enables the dendrite to receive and integrate signals from multiple sources and to process them in a highly sophisticated way.
Once the signals are received, they are transmitted to the cell body of the neuron, where they are integrated and processed before being transmitted along the axon of the neuron. The axon is a long, slender extension of the neuron that carries the electrical impulses from the cell body to the axon terminals, which are specialized structures that form synapses with other neurons or with effector cells.
In summary, dendrites are specialized structures on neurons that receive signals from other neurons or sensory receptors, and they play a key role in integrating and processing these signals before transmitting them to the cell body of the neuron. This allows the neuron to perform complex computations and respond to the environment in a highly sophisticated way.

The digestive and respiratory rely on the ___ system to
transport needed materials to the cells.
Answer:
Circulatory System
Explanation:
The digestive and respiratory rely on the circulatory system to transport needed materials to the cells.
What is circulatory system?The major job of the circulatory system is to transport oxygen, nutrients, and hormones throughout the body to the muscles, tissues, and organs. The removal of waste from cells and organs so that your body can get rid of it is another function of the circulatory system.
Through a system of arteries and veins, the heart circulates blood throughout your body (blood vessels). cardiovascular system is another name for your circulatory system. Vascular refers to blood vessels, while cardio is the word for the heart.
Blood devoid of oxygen travels along this circuit. Oxygenated blood is returned to the heart by the pulmonary veins.

The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
Answer:
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
Viscosity refers to the thickness of blood. This thickness is caused by the number of red blood cells. Thick blood travels through blood vessels at a slower rate than thin blood.
What can engineers do to protect ecosystems from invasive species ?
will mark brainliest !!!!
Answer:
By extensively filtering the water in a lake or a bay they can clear it enough to increase light penetration thus affecting benthic macroalgal communities by facilitating growth. There are numerous examples of animals and plants that function as ecosystem engineers.
In ecosystems engineers by altering their receptive environment, invading species have the potential to play a dominant role as ecosystem engineers and can have an ecosystem-level impact by hindering or facilitating other species, whether invasive or native.
What are ecosystems engineers?Ecosystem engineers are organisms that alter the physical condition of biotic or abiotic materials to affect the availability of resources (other than their own) to other species. By doing this, they alter, preserve, or even create new environments.
They can clear the water in a lake or bay sufficiently to promote light penetration, which will influence benthic macroalgal ecosystems by promoting growth.
Therefore, there are many instances of plants and animals that act as ecosystem engineers.

importance of light and chlorophyll
Answer:
importancia de la luz y la cloro fila
Answer:
Light and chlorophyll are necessary for plants to photosynthesise. Photosynthesis is when plants use sunlight and carbon dioxide to make glucose. But chlorophyll is required to make this happen. It's important that plants make their own food so they don't die, since plants are the number one source of oxygen.
