Stomata are tiny openings found in plant leaves. specialized cells known as guard cells surround the stomata and open and close the openings. when it is very hot, plants may close their stomata to prevent water loss. when plants close their stomata, what else is affected?
a) plants cannot take in the carbon dioxide they need for photosynthesis.
b) plants cannot take in the sunlight they need for photosynthesis.
c) plants cannot release glucose made in photosynthesis.
d) plants cannot take in water from the air.

A)Plants cannot take in the carbon dioxide they need for photosynthesis.

Explanation:

Stomata are tiny openings found in plant leaves. Specialized cells known as guard cells surround the stomata and open and close the openings. When it is very hot, plants may close their stomata to prevent water loss. When plants close their stomata, they will prevent water loss but photosynthesis might be affected.

Plants open and close their stomata for the exchange of oxygen and carbon dioxide during photosynthesis.

Answering the question, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis. Therefore, the correct answer is A.

Stomata can be defined as tiny openings in plant tissue that allow the exchange of carbon dioxide and oxygen. It is found in plant leaves and stems. There is a presence of some specialized cells within the stomata and the cells are responsible for the opening and closing of the stomatal pores.

Further Explanation

Stomata enable plants to absorb carbon dioxide which is important in the process of photosynthesis (the process by which green plant produce their food)

Stomata close during hot or dry conditions to limit the loss of water. In other words, they close when there is a hot or dry condition to reduce water loss.

The plants present on the land possess huge numbers of stomata on their leaves and most of the stomata can be found on the underside of the plant leaves. The position of the stomata also reduces their exposure to heat and wind. They are located on the upper surface of leaves in aquatic plants.

Therefore, when plants close their stomata, plants cannot take in the carbon dioxide they need for photosynthesis.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat. although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.

Science27 of the most iconic, jaw-dropping photos of the earth and the moon from spacedave mosher oct 1, 2018, 11: 13 am etnasa/flickrapollo 11 astronauts took this photo of earth on july 20, 1969.from the ground, earth looks like a boundless fertile plain that beckons to be explored and exploited.but astronauts would beg - and even plead - to differ."you realize that people often say, 'i hope to go to heaven when i die,'" jim lovell, an astronaut who flew on the apollo 8 and apollo 13 missions to the moon, previously told business insider. "in reality, if you think about it, you go to heaven when you're born."lovell has seen first-hand that we live on a tiny rock hopelessly lost in the void. he's also quick to tell you it's the only one we've got - a fragile spaceship for more than 7 billion people: "you arrive on a planet that has the proper mass, has the gravity to contain water and an atmosphere, which are the very essentials for life. and you arrive on this planet that's orbiting a star just at the right distance - not too far to be too cold, or too close to be too hot - and just at the right distance to absorb that star's energy and then, with that energy, cause life to evolve here in the first place. in reality, you know, god has really given us a stage, just looking at where we were around the moon, a stage on which we perform. and how that play turns out is up to us, i guess."humanity has recorded photos of earth from hundreds, thousands, millions, and even billions of miles away, some of them taken by lovell himself.these images not only scientists study our dynamic world, but also understand how a habitable planet looks from afar, which aids the search for more worlds. most importantly, however, the images underscore our peculiar existence on a mote of cosmic dust.take a moment to ponder 27 of the most arresting images of earth that humankind has ever captured from space.a
