An organism that produces its food by photosynthesis _____.
HACTEHA [7]

Answer: The correct answer for the fill in the blank is- May be placed in the Plantae kingdom.

An organism that produces food by photosynthesis can belong to three kingdoms that are Monera ( example- cynobacteria) , Protista ( example- algae) and Plantae ( example- green plants).

Thus, it is not necessary that the organism must be placed in Plantae kingdom as it may belong to any of these three.

Organisms belonging to Animalia kingdom do not perform photosynthesis.

Thus, second option is the right answer.

Through the course of evolution, plants have developed smaller gametophytes and larger sporophytes. Study the list of plants. Th
Lapatulllka [165]

Ans.

Gametophyte shows haploid, gamete-forming stage of plant's life cycle, while sporophyte shows diploid, spore-forming stage of plant's life cycle. In green algae, gametophytes and sporophytes are isomorphic (indistinguishable). In bryophytes, such as mosses, gametophyte shows dominant stage as it is most visible stage in their life-cycle. In vascular plants, such as ferns and seed plants, sporophytes show dominant stage.  

Thus, 'seed plants show briefest gametophyte stage' and 'mosses show longest gametophyte stage.'

What happens to the blood pressure when the blood vessels get longer?
liraira [26]

Answer:

:)

Explanation:

The main artery from the heart (aorta) becomes thicker, stiffer, and less flexible. This is probably related to changes in the connective tissue of the blood vessel wall. This makes the blood pressure higher and makes the heart work harder, which may lead to thickening of the heart muscle (hypertrophy).

finlep [7]

<em>Hi there, I come in behalf of jcherry99,</em>

So, first question -

This shouldn't be that much of an issue, since we have the text to help us out, but I'll try breaking it up into more simpler words:

The placenta is incide the uterus, where the baby starts forming. As you might already know, babies do not eat while they're inside woman's bellies:

So how do they feed?

They feed throught the umbilical cord.

So why is the placenta there? Why would the baby want anything apart from food?

The placenta, instead of trading food with the baby, regulates temperature, supplies it with nutrients, exchanges gas with the mother (which the mother later exchanges with the environment) and gets rid of waste.

And, food is not everything for a baby that is in the urge of developing complex muscles, bones, etc.

Second "question" -

I do not actually know what I'm supposed to do, since there is no question. But I can tell you this - the information contained in part B is correct:

The amnioic sac provides babies with a liquid which allows him to move freely in the uterus, which is very helpful. But, note that he doesn't start moving randomly, he is always in a fetus or similar-to-fetus position.

Hope it helped,
