I just need a description of what role bees play in pollination (it’s horticulture) btw
Answers
Answer:
Bees are essential for the growth of flowers and plants. They use the process of pollination where they transfer small grains of pollen from one flower of the same plant to another flower of the same species. This pollen transfer helps the flowers to get continuous growth.
Explanation:
Answer:
In the nature, plants reproduce s*exually but unlike many organisms, they do not directly mate with their opposite gender for reproduction. Their mechanism of reproduction in short is that male flowers produce pollens (yellow, powdery type thing) in thei anthers (male fower gamet) and when these pollens get contact with the female flower's stigma, the pollen fuses with the ovule and produces a fruit containing the seed.
Now how do we get these pollens moving from anthers to stigma? There are two ways. The first is by wind, when wind blows, it carries the lightweight pollens through the air and it falls onto a female flower.
the second one is by bees.
Those flowers produce nectar deep in the flower which can be sensed by bees. Bees enter the flower to collect the nectar while pollens are stuck on to its body. The bees travel to another flower for collecting nectar and when they do, the pollens from the body enter the stigma.

Which problem does the Montreal Protocol attempt to remedy?
A.The hole in the ozone layer
B.The use of fossil fuels
C.The carbon market
D.The warming of Earth
Answers
Answer:
A.The hole in the ozone layer
Explanation:
• Montreal protocol is an international treaty that was signed to control the use of substances that are resulting in the depletion of the ozone hole.
This treaty was signed in the year 1987 and became effective form 1989.
• Since the time that this treaty has come into force, there has been a significant improvement in the ozone hole that was observed over Antarctic as it's size has decreased.
• This improvement has been possible because the treaty helped to phase out chemicals such as chlorofluorocarbons, carbon tetrachloride, etc. that are responsible for ozone hole depletion.

Which of these is not a direct function of mitosis in humans?
O development from embryo to adult
O reproduction to produce the next generation
O repair of damaged tissue
O growth
Answers
Answer:
O reproduction to produce the next generation
Explanation:
Meiosis is responsible to reproduction (not mitosis). The rest of options are for mitosis.
The one that is not a direct function of mitosis is reproduction to produce the next generation. The correct option is B.
What is mitosis?Mitosis is a type of cell division in which one cell (the mother) divides to produce two new genetically identical cells (the daughters).
Mitosis is the process by which the DNA of the cell's nucleus is divided into two equal sets of chromosomes in the context of the cell cycle.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Thus, the correct option is B.

A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm.
How might the farmer’s action most likely have a negative impact on the ecosystem?
The birds will increase biodiversity of native plant species.
The birds will pollinate native species, increasing genetic variation.
The birds will consume beneficial insects, as well as the pest species.
The birds will mate with native birds and create a new species.
Answers
One of the effects of the farmer's action on the ecosystem would be that the birds will consume beneficial insects along with the pest species.
Ecological effects of biological pest controlBiological control of pest requires that a living organism that will prey on the pests are introduced into the ecosystem
However, the most effective biological control of pests has to do with introducing biological agents that are very specific in action.
Using a bird species to control insect pests may lead to beneficial insects being consumed along with the insect pest in the ecosystem. The loss of beneficial insects will create a new problem in the ecosystem.

Thebest explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.
What is genetic variation?Genetic variation refers to the differences that exists in the genes of organisms of the same species or different species.
The gene for flower color in the plants has two alleles for yellow and white flower color.
Over time, the proportion plants with white-colored flower increased while that of yellow decreased.

O justification of effort
Answers
o facial feedback
When someone replicates a emotion, they tend to feel it
Nick is smiling even though he does not feel happy and after a short time he feels happier too. This change in mood is due to facial feedback. Therefore, the correct statement is option B.
What is the facial feedback mechanism?Facial feedback is a psychological theory that suggests that the expression on a face of a person can influence their emotions and mood also. Therefore, when a person smiles even when they are not feeling happy, it can trigger positive emotions in the brain that change in mood.
Nick is smiling even though he is not feeling happy. Therefore, this act of smiling can trigger positive emotions in his brain and changes his mood because of the facial feedback mechanism.
However, bottom-up processing is the processing of sensory information from the environment to create a perception, while selective encoding is a process of selectively attending to and encoding certain aspects of a stimulus while ignoring others.
Therefore, Nick is smiling even though he does not feel happy and feels happy after a short time due to facial feedback.
