Answer:
No, you would not expect to find a muscle tissue in a plant.
Explanation:
Why? because muscle tissues are built up of cells that receive and react to signals sent from the brain, though some plants (usually carnivorous or touch sensitive) do have different ways of movement. But again, these methods are *Not* muscle tissues!
Muscle tissue is not found in plants. Plants have different types of specialized tissues such as vascular and ground tissue.
Explanation:Would you expect to find a muscle tissue in a plant? Why or why notNo, you would not expect to find muscle tissue in a plant.
Plant cells are different from animal cells and do not have the specialized structures and proteins required for muscle movement.
Instead of muscle tissue, plants have different types of specialized tissues, such as vascular tissue for transporting water and nutrients, and ground tissue for storage and support.

In the Watson-Crick model of a double helix, the "steps" of the "spiral staircase" are composed of:
A- sugars
B- nitrogen bases
C- phosphates
Answer:
Explanation:
DNA’s famous double helix is often depicted as a spiral staircase, with two long strands twisted around each other and steps composed of four chemical building blocks called bases. Each of these bases contain rings of carbon, along with various configurations of nitrogen, oxygen, and hydrogen. The arrangement of these atoms allow G to pair with C and A to pair with T, like interlocking gears in an elegant machine.
Answer:
The answer is C
Explanation:
If the parent strand of DNA is 5'atggcttac'3 what will the daughter strand be?
Answer:
If the parent strand of DNA is 5' atggcttac 3', then the daughter strand will be 3' taccgaatg 5' .
Explanation:
The DNA (deoxyribo nucleic acid) has a double helix structure with the two strands running in antiparallel directions to each other, and the nitrogenous bases in them are adenine (A), thymine (T), cytosine (C) and guanine (G). In DNA, the complementary base pairs are adenine (A) with thymine (T) and cytosine (C) with guanine (G).
DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. The process where part of the DNA is saved during replication is known as semi conservative replication. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. During DNA replication, an enzyme known as DNA helicase breaks the hydrogen bonding between the base pairs, adenine with thymine and cytosine with guanine. This unwinds the parental DNA double helix into two separate strands and thus creates a Y shaped replication fork, where the template for replication begins.

How do phythophtora infestans reproduce
Answer:
Phytophtora infestans is host-specific pathogen and can reproduce both asexually and sexually.
Explanation:
Asexually: The spores (sporangia) of P. infestans are transported via wind or water. Once they land on the plant tissue, the zoospores are released. When conditions are warmer, zoospores are germinated. Here, a germ tube is formed which penetrates into the plant tissue and allows the newborn to get nutrients from plant sap for its own growth and development.
Sexually: Sexual reproduction takes place when both male and female are present. Here, antheridium and oogonium nuclei (haploid) fuse together to form a diploid oospore. The oospore then develops into sporangium and the rest of the cycle follows the same pattern as of asexual reproduction.

sexual reproduction?
A It requires only one parent.
B It can remove harmful traits from a
population.
C It involves cells formed through mitosis.
D It increases the mutation rate.
Answer:
"It increases the mutation rate" is an advantage of sexual reproduction
Explanation:
The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.

Ore is feeling cold, and he is clenching his fists together to stay warmer. He then releases his grip a little bit because he feels that it is too tight. Which two particular sensory receptors are activated through this experience?
Explanation:
The thermoreceptors in Ore’s skin detect low blood temperatures in the skin blood vessels due to the loss of heat from the skin to the cold environment. The receptors send signals to the brain, and the brain sends motor signals to the muscles (including those of the fist) to react to the stimuli. This is why Ore clenches his fists to reduce heat loss.
However, as his clenched fist gets tighter the mechanoreceptors in the skin become depolarised when the signal (the pressure) surpasses the required threshold. This sends a signal to the brain and the brain responds by sending a motor signal to the fist muscle so Ore relaxes the fist a bit and this softens the clenching.

Plants are able to continue to grow and develop once the starch supply in the seed is gone, because they have chloroplasts and use light energy to make more food. The correct option is C.
What is chloroplast?Since photosynthesis occurs in chloroplasts, which are organelles in plant cells that contain chlorophyll, chloroplasts are essential for life on Earth.
Proplastids give rise to chromoplasts, leucoplasts, and other plastids, including chloroplasts.
Organelles found in plant cells called chloroplasts use the photosynthetic process to change light energy into relatively stable chemical energy.
They maintain life on Earth in this way. Additionally, chloroplasts support a variety of metabolic processes in plant cells, such as the production of starch, fatty acids, and membrane lipids.
When the starch supply in the seed is depleted, plants can still grow and develop because they have chloroplasts, which utilise light energy to produce more food.
Thus, the correct option is C.
