jeka57 [31]3 years ago
6 0

Answer:

Explanation:

During a physical change, the arrangement of particles may change but the mass, number of atoms and number of molecules will stay the same. ... During a chemical change, the mass and number of atoms is conserved, but the number of molecules is not always the same. Chemical reactions involve large changes in energy.

How can you tell if a protist belongs to eubacteria or archaebacteria?
zhuklara [117]
Protists are unicellular eukaryotes, whereas Eubacteria and Archaebacteria are unicellular prokaryotes.
Eubacteria and Archaebacteria belong to kingdom Monera; whereas Protists belong to kingdom Protista.
All Monerans have prokaryotic cell structure. Protists have eukaryotic cell structure and are unicellular.
Protists either lack cell wall or have cell wall made up of cellulose.
Eukaryotes have cell wall made up of peptidoglycan or murein.
In Archaebacteria cell wall lacks peptidoglycan but contains proteins and non-cellulosic polysaccharides.
Protists have typical sexual reproduction involving fusion of gametes. In Eubacteria and Archaebacteria typical sexual reproduction is absent.
Cell division is mitotic type in Protists and amitotic in Eubacteria and Archaebacteria.

The process whereby neutrophils and other white blood cells are attracted to an inflammatory site is called ________.
VLD [36.1K]
<span>The process whereby neutrophils and other white blood cells are attracted to an inflammatory site is called as <u>chemotaxis</u>. It is a process by which inflammatory cells migrated or attracted towards other cells in the blood. It's like a phenomena of negative cells attracted to positive cells. Technically speaking, it's a movement of cells in response to chemical cells. It's an important response common in cellular biology. It's also a process by which cells translate chemical information.</span>

Heterozygotes at the sickle-cell locus produce both normal and abnormal (sickle-cell) hemoglobin (see Concept 11.4). When hemogl
Stels [109]

Answer:

In an individual's molecular and cellular level, the heterozygote alleles are preferred over the homozygote alleles. In humans, the heterozygote alleles are found at a locus of beta polypeptide subunit of hemoglobin, while on the other hand, the homozygous alleles found at a similar locus are prone to sickle cell disease.  

The individuals carrying homozygous alleles exhibit sickle-shaped RBCs and they also possess low oxygen-carrying capacity, which ultimately results in brain, kidney, or heart failure. However, in the case of heterozygous alleles, the configurations of RBCs are of two kinds, that is, normal shaped and sickle-shaped. Thus, there are not enough sickle-shaped cells to result in the condition.  

The heterozygote alleles are resistant to malaria, thus, in tropical areas, where malaria is a prime issue the heterozygote alleles are preferred over the homozygote dominant alleles as they are vulnerable to the infection and over the homozygote recessive alleles who has sickle cell disease.
