Answer:

an endoskeleton is a skeleton on the inside of a living creature. look at endo like enter, its on the inside! an exoskeleton is on the outside of a living creature. think of exo as exit, its on the outside! animals with endoskeletons are like dogs, cats, fish, and raccoons. animals with exoskeletons are like spiders, ants, crabs, and snails.

Answer:

The place where the axon of one neuron meets the dendrite of another is called a synapse. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.

Answer:

Plant cell

Explanation:

The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright.

Answer:

Natural selection, mutation, and genetic drift are random events.

Explanation:

A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.

Answer:

Echinoderms evolved from animals with bilateral symmetry. Although adult echinoderms possess pentaradial, or five-sided, symmetry, echinoderm larvae are ciliated, free-swimming organisms that organize in bilateral symmetry which makes them look like embryonic chordates.

Answer:

B, one month

Explanation:

It really depends on what kind of Small vertebrates are in question, frogs take about 12 weeks for birds it takes about a month.

Answer:It is well known that age influences organism mobility. This was demonstrated in vertebrates (such as mammals and birds) but has been less studied in invertebrates with the exception of Drosophila and the nematode Caenorhabditis elegans. Here we studied the influence of age on the mobility of the orb-weaving spider Zygiella x-notata during web construction. The orb-web is a good model because it has a characteristic geometrical structure and video tracking can be used to easily follow the spider’s movements during web building. We investigated the influence of age (specifically chronological age, life span, and time till death) on different parameters of spider mobility during the construction of the capture spiral (distance traveled, duration of construction, spider velocity, spider movement, and spider inactivity) with a generalized linear model (GLM) procedure adjusted for the spider mass. The results showed that neither chronological age, nor life span affected the mobility parameters. However, when the time till death decreased, there was a decrease in the distance traveled, the duration of the construction of the capture spiral, and the spider movement. The spider velocity and the time of inactivity were not affected. These results could be correlated with a decrease in the length of the silky thread deposited for the construction of the capture spiral. Spiders with a shorter time till death built smaller web using less silk. Thus, our study suggests strongly that time till death affects spider mobility during web construction but not the chronological age and thus may be a good indicator of senescence.

Another reason is that Zebras and Antelope love the open African savannas – in comparison to Kudus or other antelopes that prefer the thicker bush. Being out in the open obviously makes these two antelope species very vulnerable – therefore they are teaming up and are best buddies.

Explanation:

Option C and E are  the diagram which correctly portrays the direction of the prevailing winds in each latitude band

Latitude and longitude are two most important terms which are the coordinates that, together, tells exactly location of an object on the surface of the Earth.

Latitude tells the position of the object or anything  between the North Pole and the South Pole where equator is zero degrees, the North Pole is 90 degrees North, and the South Pole is 90 degrees .

Parallels called as latitude lines which run across the Earth from east to west at a constant latitude, for example would be the equator, which is at zero degrees of latitude

Latitude is major indicator of navigation because the path of the sun is different depending on the object's latitude, so it varies based on the time of year.

Explanation:

Answer:

Chloroplast.

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, ...

Phtosynyhsis.

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process

Seeds.

Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions.

Roots.

Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
