Answers

Answer 1

Answer: The domestication of plants and animals is a hallmark of the neolithic era - D. This was the time when humans first started domesticating different animals and more importantly, started growing crops whichenabled them to start living on one location and staying there for longer times.

Answer 2

Answer: The domestication of plants and animals is a hallmark of the neolithic era.
The answer is D.

Where sugar concentration is high, what is the source of water taken in by phloem

Answers

let's start with the fact the the phloem of a plant is a special tissue that mainly transports food sources for the plant. one of the products it transports is various sugars - more commonly known as sap. the higher the concentration of sugars, the lower the concentration of water. in that case, the plant slows down on sugar making as it has a surplus, and once the sugars dilute within the sap and water's been taken in, the plant goes back to sugar making.

The classification levels of a human are listed below from largest to smallest. Eukarya
Animalia
Chordata
Mammalia
Primates
Hominidae
Homo
sapiens
Which level of biological classification do Mammalia and Hominidae represent, respectively?

A)class and family

B)order and class

C)family and species

D)species and kingdom

Answers

Ans.

Biological classification of a species, there are eight levels from largest to smallest, which include domain, kingdom, phylum, class, order, family, genus, and species.

According to this classification system, modern humans can be classified as:

Domain (Eukarya), Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Primates), Family (Hominidae), Genus (Homo), Species (sapiens).

Thus, levels of biological classification, represented by Mammalia and Hominidae are class and family, respectively.

Class and Family is the answer

All proteins are synthesized by ribosomes in the cell. some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. most proteins made by free ribosomes function in the cytosol. proteins made by bound ribosomes either function within the endomembrane system or pass through it and are secreted from the cell. which of the following proteins are synthesized by bound ribosomes?

Answers

ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.

Photosynthesis is a process in which _______ energy is converted to _______ energy.

Answers

Photosynthesis is a process in which light energy is converted to chemical energy.

Organisms, such as plants, that carry out photosynthesis absorb light from the Sun and, through a series of chemical reactions, produce sugar (glucose) molecules. These sugar molecules may be stored by the photosynthetic organism, or the chemical bonds in the sugar can be broken down by the organism to release energy for its life processes.
