While biodiversity includes the number of species in a given area, it also includes phylogenetic lineages.

<h3>What is biodiversity, exactly?</h3>

The variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural environment are all included in what is known as biodiversity. These various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life.

<h3>What kind of biodiversity is that?</h3>

As a group of distinctive living entities having the capacity to reproduce with one another, biodiversity. Blue whales, white-tailed deer, white pine trees, sunflowers, and minuscule germs that are even too small to be seen with the eye are a few examples of species.

<h3>How can biodiversity be preserved?</h3>

Purchasing fewer products and ensuring that the ones you do purchase have a minimal impact on biodiversity investing in initiatives to advance biodiversity.

What role does the animals play in primary succession?
dsp73

Answer:

The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants.

Which organelle stores the information that determines an individual plant leaf shape.
sladkih [1.3K]

Genetic relationships, gene expression patterns, microRNAs, and active hormonal controls all contribute to the genetic foundation of leaf form. organelle 1 is large vacuole, 2nd organelle is mitochondria, organelle 3 is nucleus and organelle 4 is cell wall.

The size of the cell and the number of cells determine the size of the leaf. Plant hormones, growth-regulating factors (GRFs), TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP), WUSCHEL RELATED HOMEOBOX (WOX), and other regulatory factors control cell expansion and differentiation [3,4].

Rough E.R. makes and transports substances through the cell and Smooth E.R. does not have ribosomes; Ribosome make protein for the cell.

11. Consider the sequence shown, determine the complementary RNA and the amino acids
mezya [45]
ATG, CAT, AAA, CGT, GTG

adenine, thymine, guanine
cytosine, adenine, thymine
adenine
cytosine, guanine, thymine
guanine, thymine

for RNA, you’ll just do the opposite of what the DNA strand says..... so A pairs with T and C pairs with G

for the actual acids, you’ll just list the names of the RNA sequence, which could be adenine, thymine, guanine, or cytosine
