Answer:
perform functions that tissues cannot carry out on their own
Explanation:
In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.
A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.
Answer:
Phosphofructokinase will be activated
Explanation:
Phosphofructokinase (PFK-1) is an enzyme of glycolysis that catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate. The enzyme uses ATP as a phosphate group donor for this phosphorylation. It is a regulatory enzyme and the reaction catalyzed by it is irreversible. The activity of PFK-1 is increased whenever the cell’s ATP supply is depleted or when the ATP breakdown products, ADP and AMP, are in excess.
Answer:
Because the gametes implemented in fertilisation are haploid in nature, in the case of humans, mature gametes contain 23 chromosomes instead of 46 which will then combine with another parents' 23 chromosomes during fertilisation, i.e: 23 (dad) + 23 (mom) = 46 (zygote)
Explanation:
A regular somatic cell has 46 chromosomes, 2n, 2 alleles but the gametes have 23 chromomes, n, 1 allele. The usual significance of this is so that there is diversity in the offspring and the offspring can gain characteristics (bad or good) from both parents.
Correct answer - No, because they can’t make their own food.
Why? - Prions, however, are not living organisms. Prions are infectious proteins. ... Prions will then cause tissue damage and cell death to surrounding areas. Prion diseases are neurodegenerative, attacking the brain and are characterized by "holes" in the tissue.
If the web happened to look like this one I attached then the anwser would be shrubs. If you take a look at the arrows the shrubs energy is moving to rats, insects and lizards which in turn feeds the coyotes. The starting point is shrubs and in general most food webs start with plants.
