Describe two problems a plant might encounter during reproduction
Answer:
During reproduction plant might experience absence of pollinators or presence of low temperature
Explanation:
Following can be the problems a plant might encounter during reproduction
Presence of Low temperature for long time: Due to presence of low temperature during the reproduction of plants for long period of time it will break its dormancy and freeze the blossom or developing fruitAbsence of pollinators: As e know pollinators play a vital role in reproduction. In the absence of Pollinators (i.e., beans) plants are not able to exchange the nectar carryingPlant reproduction takes place through the asexual and sexual process called pollination. They can either self-pollinate or cross-pollinate.
Reproduction needs the fusing of both the male and female gametes and fuse to male the seed that bear the fruit. During reproduction, the plants may face a lack of pollen grains and the presence of low temperature.Learn more about the two problems a plant might encounter during reproduction.

What is a temperature graph?A climate graph displays yearly temperature and precipitation statistics for a particular location. Temperature is measured using the numbers on the left-hand side of the chart. The average temperature for each month is plotted on the graph with a red dot and the dots are then connected in a smooth, red line.
What graphs are used in weather?Two common types of graphs are bar graphs and line graphs. Bar graphs use vertical or horizontal rectangles (bars) to represent a specified quantity. Line graphs use points to identify values, and then connect each point with a line that shows the fluctuations in the data.

What is the diploid of the zygote produced by fertilization—haploid or diploid?
Answer:
"Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

Descrlbe the relationshlp among the agents of disease, the Infectious dose, and the health of
a host.
Answer:
The number of pathogens that are required to infect a host, termed infective dose, varies dramatically across pathogen species. It has recently been predicted that infective dose will depend upon the mode of action of the molecules that pathogens use to facilitate their infection. Specifically, pathogens which use locally acting molecules will require a lower infective dose than pathogens that use distantly acting molecules. Furthermore, it has also been predicted that pathogens with distantly acting immune modulators may be more virulent because they have a large number of cells in the inoculums, which will cause more harm to host cells. We formally test these predictions for the first time using data on 43 different human pathogens from a range of taxonomic groups with diverse life-histories. We found that pathogens using local action do have lower infective doses, but are not less virulent than those using distant action. Instead, we found that virulence was negatively correlated with infective dose, and higher in pathogens infecting wounded skin, compared with those ingested or inhaled. More generally, our results show that broad-scale comparative analyses can explain variation in parasite traits such as infective dose and virulence, whilst highlighting the importance of mechanistic details.

what part of the muscle cell most closely regulates protein synthesis?
1) Endoplasmic Retriculum
2)Lysosome
3)Nucleus
4)DNA
Answer:
ENDOPLASMIC RETRICULUMExplanation:
Thank uhh!!!!!!!!❤
Muscle cell most closely regulates protein synthesis it follows that ribosomes, which are found in the cytoplasm and rough endoplasmic reticulum, are where protein synthesis or translation of m-RNA to protein occurs, hence option 1 is correct.
What is the endoplasmic reticulum?Sarcoplasmic reticulum is a specific type of ER found in skeletal muscle (SR). The SR is essential for both the contraction of muscles and the preservation of muscle homeostasis because it serves as a calcium storage depot and controls the release of calcium during myofibrillar contraction.
Ribosomes: Ribosomes are crucial cell organelles involved in the production of proteins. Proteins and RNA found in ribosomes assist in translating genetic instructions into proteins.
Therefore, the endoplasmic reticulum part of the muscle cell most closely regulates protein synthesis.

Explain why transboundary environmental threats like pollution are a problem for both parties, even if one community is principally responsible for the pollution.
Answer:
Due to its spreading nature.
Explanation:
Transboundary environmental threats like pollution is a problem for both parties i. e. one that is producing pollution and the other which is not producing it, because pollution can't remain at one place and spread from one part to another part of the earth due to open environment. So due to its spreading, it affected both the producing and non-producing parties.
Answer:
Even when pollution originates on one side of a border, it often spreads through the environment beyond the point of origin, becoming a shared problem. It is important to track the sources of pollution to identify the policies and sources for prevention efforts, but regardless of the source of pollution, once a border area becomes polluted, the pollution is a health threat for all individuals on either side of the border.

would happen if gametes were diploid? Use evidence to support your claim
Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes). During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n)

What are Somatic cells?During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n).
The body's somatic cells are those that are neither sperm or egg cells (which are called germ cells).
Somatic cells in humans are diploid, which means they have two sets of chromosomes, one from each parent. Somatic cell DNA mutations can have an impact on an individual, but they cannot be passed on to the individual's progeny.
Therefore, Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes).

Ariana is trying to complete her flashcards for an upcoming quiz on photosynthesis and cellular respiration. On the front of each card she has written the reactants, and on the back she is writing the products. Her photosynthesis card is complete, but she is missing the back of her cellular respiration card. She asks her teacher what infomation she is missing. Which statement explains where Ariana's teacher will direct her to for help? The teacher will direct her to the anaerobic respiration card because they have identical products. The teacher will direct her to the back of the photosynthesis card because the two processes are identical. The teacher will direct her to the front of the cellular respiration card because cellular respiration has the same products and reactants. The teacher will direct her to the front of the photosynthesis card because photosynthesis reactants are the products of cellular respiration.
Answer:
The teacher will direct her to the front of the photosynthesis card because photosynthesis reactants are the products of cellular respiration.
Explanation:
Cellular respiration is an aerobic process in which energy is released by breaking down glucose ( C6H12O6 ) and other molecules.
Photosynthesis is the process in which plants make their own food in the presence of sunlight by utilizing water (H2O) and carbon dioxide (CO2) and convert it into oxygen (O2) and glucose (C6H12O6 ).
equation of cellular respiration is: C6H12O6 (glucose) + 6O2 (oxygen) => 6CO2 (carbon dioxide) + 6H2O (water) + energy
equation of Photosynthesis: 6CO2 (carbon dioxide) + 6H2O (water) +energy => C6H12O6 (glucose) + 6O2 (oxygen)
Hence, cellular respiration is a reverse reaction of photosynthesis and the photosynthesis reactants are the products of cellular respiration.
