When a plant generates food through photosynthesis, this food
A.
is always used as soon as it is converted into a form the plant can use.
OB
can be used immediately or stored for later use.
C.
can cause the plant to gain excess layers of fat.
OD
is stored for a short period of time, usually about three weeks,
Answer:
B:because plant will make the food,store it,or eat it.usually the plant will stored the food for the winter,because of the soil being frozen and barely any sunlight,it will make it hard for the plant to make more food during photosynthesis,sometimes the plants will die but come back when it is springtime.Once food is made it is used or saved for later use for energy.
Answer:
can be used immediately or stored for later use.
Explanation:
Energy generated through photosynthesis can be used immediately or stored for later use depending on the needs of the plant in its environment.
Sometimes, a plant needs to immediately put this energy into growing new branches or leaves. Other times, such as when a cold winter is approaching, it might be better for the plant to store the energy for later use

Much of the Florida landscape is built upon limestone. Frequent rains seep down and erode the limestone as the rainwater travels to underground caverns or aquifers. Which of the following landforms could be created as a result of this process?
Answer:
potholes/ sinkholes. most likely sink holes. i dont have options
Explanation:
In the conifer forest just below the alpine zone of a mountain top, two closely related species of birds that feed on small flying insects have been living together for millions of years. A local naturalist notices that the beak sizes differ on the two birds. The species that eats mosquitoes has a small delicate beak, and the species that eats robber flies (bigger than mosquitoes) has a very large beak. By accident, the naturalist stumbles upon a fossilized bird on the mountain that looks like it could be the ancestor of both species except its beak is neither small nor large, but intermediate in size. What principle could be at work in shaping the beaks of these birds? a. competition b. ecological niche development c. coevolution d. character displacement e. all of the above
Answer: d. character displacement
Explanation:
Character Displacement this is an evolutionary divergence which usually occurs when two similar species inhabit the same environment. This circumstance occurs where differences among similar species whose circulation in an environment overlap geographically are feature in regions where the species co-occur, but tend to be minimized or lost where the species' circulations do not overlap. Which is same case as that of the birds.

Determine whether each activity impacts land resources in a positive or negative way. Drag each term to the correct
category.
desertification
Positive Impacts
Negative impacts
reforestation
laws and regulation
habitat restoration
erosion
urbanization
deforestation
Answer:
desertification - negative impacts
Reforestation - positive impacts
laws and regulation - positive/negative impacts
habitat restoration - positive impacts
erosion - negative impacts
Urbanization - negative impacts
deforestation - negative impacts
Explanation:
Desertification is a process in which productive lands become a dry, unproductive one as a result of humans or natural activities such as drought, deforestation, etc. It impacts land resources negatively in that land generally becomes unproductive and unsupportive to other lives.
Reforestation is a process of artificially creating forest where one has been removed or where none existed before. It involves the planting of trees and leads to the creation of new land resources such as habitats, water sheds, etc.
Laws and regulations can impact land resources either positively or negatively depending on the type of laws. Laws that promote land conservation positively impact land resources while those that promote the wanton use of lands negative impact land resources.
Habitat restoration refers to activities geared towards restoring habitats of organisms that have been degraded by human or natural activities. Habitat restoration positively impacts land resources as natural processes are directly impacted positively.
Erosion involves the removal of topmost layer of soils by running water or wind. It negatively impacts land resources by rendering land unproductive impacting the protective nature of soil on other resources such as watershed, etc.
Urbanization refers to the process of actively developing an area vis a vis the construction of more buildings and other infrastructures to make a place more urban. Land resources are negatively impacted in the process as most often requires the conversion of lands to non-forested uses.
Deforestation is the removal of forest layers for non-forest uses. It negatively impacts land resources such as habitat removal, lower biological diversity, protection of water sheds etc.

Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient across the inner mitochondrial membrane generated by electron flow is used to synthesize ATP. B) Uncouplers dissipate the electrochemical gradient but electron transport continues without ATP production. C) Inhibitors disrupt electron flow as well as ATP synthesis. D) A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP. E) ATP synthesis occurs via simultaneous conformational changes in protein subunits containing catalytic sites.
Answer
D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP
Explanation:
Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.
Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.

Answer: 1. independent , 2 . dependent
The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.
What is immune system?
The immune system protects our body from foreign invaders like bacteria, viruses, and fungi, and other toxins.
In general 2 types of the immune system observed in human body.
The innate immune system rapid inheritable response system consist major organs like skin, the eye's cornea, and the mucous membrane that lines the respiratory, gastrointestinal, and genitourinary tracts.
Secondly, the acquired immune system work with the innate system to make a special proteins named antibodies to protect our body from a specific invader.
Human immune system show variation in their production of immune components like cytokines play critical roles and it vary from person to person.
Hence, The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.

A lot of echinoderms are named after flowers true or false
Answer:
False, it is only represented by one class: Crinoidea (sea lilies).
Explanation:
Echinoderms (phylum Echinodermata) are marine organisms that comprises more than 6,000 species. These animals are deuterostomes that are differentiated to have an ambulacral vascular system and a pentameric symmetry. Echinoderms are divided in the following classes: 1- Ophiuroidea (snake stars), 2-Asteroidea (sea stars), 3-Crinoidea (sea lilies), 4-Holothuroidea (sea cucumbers) and 5-Echinoidea (sea urchins), which can be easily distinguished by anatomical and ecological characteristics.
. Your lab technician was to determine the ash content of buttermilk by conventional dry ashing. The technician weighed 5 g of liquid buttermilk into one weighed platinum crucible, immediately put the crucible into the muffle furnace using a pair of all stainless steel tongs, and ashed the sample for 48 h at 800 °C. The crucible was removed from the muffle furnace and set on a rack in the open until it was cool enough to reweigh. (4 marks)
a. What errors were made in the preceding method (there were several)?
b. What were the likely results of these errors?
Answer:
Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications
The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.
a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:
Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.The sample should be ashed for 12-18 hrs , more than this can damage the required ash content.platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.b. The result that occur due to above errors such as the temperature, time, tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.
