Answer:
d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric
Explanation:
There are four primary types of tissues in living organisms. Epithelial and connective tissues are two of those four types of tissues. Epithelial tissues are made up of closely packed cells that serve functions such as absorption, secretion, protection, etc while connective tissues are composed of cells, ground substance, and protein fibers that serve supportive functions.
The cells of epithelial tissues are so closely packed to one another that there is hardly space in their extracellular matrix for materials. However, on the contrary, connective tissues are made up of cells that have room for large quantities of extracellular matrix. Hence, the cells that make up connective tissues are dispersed into matrix.
Answer:
distal convoluted tubule
Explanation:
This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.
The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).
The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
I'm not sure but I think the producers are the shrubs and the elm tree.
