We should first define all of the answer choices to be able to eliminate and come up with the correct answer. Chromosome functions to carry the genetic information and contains DNA molecules. DNA molecules are the basic building blocks of chromosomes that serve to carry the genetic information. Receptor is a molecule on the surface of cells that receives signals from the extracellular environment and leads to the change...
Our nervous system is divided into two categories: Autonomic and Somatic. Autonomic includes all the processes that occur automatically without our conscious thoughts such as breathing and heartbeat. Somatic, on the other hand, deals with conscious processes such as walking, running, raising your hand etc.
Autonomic nervous system can be further divided into two categories: Sympathetic and Parasympathetic.
A cell nucleus is a membrane enclosed organelle found in eukaryotic cells. Nucleus contains all of the genetic information a cell has, in the form of DNA. It also contains various proteins. For example proteins, histones, are what DNA strands wrap around to form chromosomes. Furthermore, both DNA replication as well as transcription happens in the nucleus. Transcription is the process of creating RNA from DNA template....
For centuries humans have cleared native grasslands and forested areas to farm on as well as built houses and cities on. It came with benefits but also with a cost. Since the question is asking us about negative effect we can eliminate any answers that sound like benefits such as 2,3,4. Indeed by eliminating g
The virus that causes bird flu can attach to the cells of the lower part of the respiratory system in humans, but not to the cells of the upper part of the respiratory system. The most likely reason for this is that these two groups of cells have different
(1) DNA codes in their nuclei
(2) enzymes in their mitochondria
(3) amounts of water in their cytoplasm
(4) receptor molecules on their membranes
An energy-rich organic compound needed by organisms is
Answer and Explanation:
In order for a compound to be organic it must contain a very important element: Carbon. This can eliminate choices 1 and 3 since the formula for water is H2O and oxygen is O2. A compound that is rich in energy is glucose, choice 4. The formula for glucose is C6H12O6. Animal bodies break down glucose in a...
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc...
