what does a root hair cell do
Answer:
Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
The vesicles involved in endo/exocytosis are surrounded by a phospholipid membrane.
A. True
B. False
Answer:
A. True
Explanation:
The vesicle travels to the cell membrane. The vesicle fuses to the plasma membrane, during which the two bilayers merge. The vesicle's contents are released into the extracellular space. The vesicle either fuses with or separates from the cell membrane.

Which class of point mutation produces a product with the same amino acid sequence as the wild-type polypeptide?
Answer:
The correct answer is - silent.
Explanation:
Silent mutation is a point mutation that takes place by a single change in a single base nucleotide of nucleic acid and it may or may not change the aminoacid sequence as the wild type protein.
This does not result in any phenotypic or functional change in the protein of the organism. It is a class of point mutation. This change can be substitution in base.
What is the purpose of mitosis?
Answer:
Mitosis creates more diploid cells by copying each chromosome and moves it to the other side of the cell.
Explanation:
This lets the cell get divided straight down the middle.

Climate change has begun to affect insects as food resources have started disappearing . The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.

A possible hypothesis for this situation is that tank 1 contains denitrifying bacteria, tank 2 contains nitrite nitrifying bacteria, and tank 3 contains ammonia nitrifying bacteria.
What is a hypothesis?A hypothesis, which is a common term used in experiments refers to a possible explanation for the results or phenomenon observed. In this case, a hypothesis needs to focus on the type of bacteria that are present in each of the tanks.
This means that to write a hypothesis we need to relate the type of bacteria to each of the tanks.

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
Explanation:
To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices
Answer:
The missing answer choices are:
a. hypotonic
b. isotonic
c. osmosis
d. hypertonic
The correct option is d. hypertonic
Explanation:
A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.

Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25
Could someone please tell me if this is mold or not? I think it is but honestly I know nothing about that.
Answer:
It would be Penicillium or Aspergillus, if it is even mold. They are some of the fastest growing molds (usually within 24 to 48 hours) and require very little moisture for their colonies to develop. I haven't ever seen mold
It's usually not possible for you to remove it from wood, but you are going to want to call someone to get rid of it. You don't know what exactly it is and buying fungicide may help.
