Varvara68 [4.7K]3 years ago
3 0

Explanation:

-<u>Carbohydrates </u>act as signals or markers to help cells recognize one another.

Carbohydrates are organic macromolecules with a range of functions within organisms. They may act as energy storage, structural support, and signal molecules. Together with transmembrane proteins embedded within the membrane from the extracellular fluid to the cytoplasm, they form glycoproteins (proteins attached to carbohydrates) which function as cell surface markers .

 

Further Explanation:

Carbon, is the backbone of all biological life on Earth. It contains 6 electrons, with 4 on its valence shell, and thus, readily forms covalent bonds with other elements. Covalent bonding involves the sharing of electrons; in nature, this occurs with hydrogen,oxygen, nitrogen, and phosphorus as highly flexible single bonds capable of rotation; rigid, non-rotating  double; and very strong triple bonds. Carbon compounds form rings, and long branched chains- thus, carbon can form macromolecules in nature.

In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Basic makeup: C, H, O -with many polar OH groups

1. _________reproduction is a means of creating new individuals solely by________ the form of cell division that creates genetic
mixer [17]

Answer:

1. asexual, mitosis  2. sexual  3. gametes, meiosis  4. haploid 5. sex cells

Explanation:

Asexual reproduction is the form of reproduction that occurs whereby there is no fusion of gametes or a change in the number of chromosomes. The produced daughter cells are genetically similar to the parent. the form of cell division that occurs here is through a process of mitosis.

Different organisms adopt different type of asexual reproduction including binary fission, spore formation, fragmentation etc.

Sexual reproduction in contrast generates genetically unique organism through the fusion of two different organisms sex cells. To accomplish sexual reproduction, gametes that are haploid through a process of meiosis must be produced which are the egg cell and the sperm cells (the sex cells). These haploid cells are produced only in the germ cells to ensure the production of a diploid zygote.

As with all multicellular organisms, homeotic genes in plants control morphogenesis (how the tissues and organs of the plant are
joja [24]

Answer:

a. True

b. True

c. False

d. True

e. False

f. False

g. True

Explanation:

The homeotic genes refer to evolutionarily conserved genes that modulate the development of different structures in organisms of the same groups (in this case, plants).  Moreover, homeobox genes are genes that encode transcription factors involved in the regulation of development in eukaryotic organisms. The knotted1 (<em>kn1</em>) gene is a plant homeobox gene is a member of the <em>kn1</em> homeobox (<em>knox</em>) gene family, which is responsible for maintaining indeterminacy and preventing cellular differentiation. In maize, <em>kn1</em> plays a key role in maintaining the cells of the shoot apical meristem in an undifferentiated state, being mainly expressed in shoot meristems during postembryonic stages of shoot development. It has been observed that maize mutant plants where <em>kn1</em> is ectopically expressed (i.e., in tissues in which this gene is not normally expressed) exhibit proximal-distal patterning defects.

Lostsunrise [7]

Answer:

<h3>Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.... </h3>
