Why is human blood red and not blue such as squid & snail blood?
Hemoglobin contains copper that gives the blood the red color when exposed to
oxygen
Hemoglobin contains magnesium that gives the blood the red color when
exposed to oxygen
Hemoglobin contains iron that gives the blood the red color when exposed to
oxygen

Answers

Answer 1

Answer:

it contains iron that gives it the red color when exposed to oxygen

Answer 2

Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.

What is hemoglobin?

Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.

Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.

Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

A population of beetles is mostly composed of individuals with the dominant green color, but there are several with the recessive brown
color. A displaced species of bird moves into the habitat and preferentially preys upon the green beetles. Over time, what can be expected
to happen to the beetle population?
O A. The beetles will migrate to avoid being eaten by the birds in the habitat.
OB. The beetle population will become extinct.
O C. The beetle population will stabilize because the birds will not eat more beetles than necessary to maintain ecological balance.
O D. The brown beetles will become more common.

Answers

The green beetles will decrease in number while the brown beetles will become more common.

According to Darwin's theory of evolution, organisms that are better adapted to their environment are able to live longer and survive long enough to reproduce thereby perpetuating their favorable characteristics in the population.

Since the green beetles are more common but they are preferentially preyed upon by the invasive bird species, the green beetles will decrease in number while the brown beetles will become more common.

One gene in the human genome may be expressed at a much higher level than another. Can differences in types of cis elements present account for this

Answers

Answer:

No, CREs usually don't account for differences in gene expression levels.

Explanation:

Cis-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene transcription. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate gene expression levels.

Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.

what is located in the autonomic nervous system

Answers

Answer:

It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Explanation:

The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS). Generally, the SNS and PNS motor pathways consist of a two-neuron series: a preganglionic neuron with a cell body in the CNS and a postganglionic neuron with a cell body in the periphery that innervates target tissues. The enteric nervous system (ENS) is an extensive, web-like structure that is capable of function independently of the remainder of the nervous system. It contains over 100 million neurons of over 15 morphologies, greater than the sum of all other peripheral ganglia, and is chiefly responsible for the regulation of digestive processes.

4. Describe the interrelationship between cell, tissue and organ of human body. ​

Answers

Answer and Explanation:

Cell: Molecules get grouped in alive cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells, their membranes delimitate them and protect them, constituting a selectively permeable barrier, receives signals from the exterior and responds in different ways to the different signals. There are different cells with different sizes, shapes, and forms.        

Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera.

Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function.                                                                        

Organ systems: When different organs get associated and work together, they become a system. Working together in a stable way organs maintain homeostasis.

what organelle processes and sorts proteins to be shipped

Answers

Answer: The Golgi apparatus

Explanation: The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.

The organelle that processes and sorts proteins to be shipped is the Golgi apparatus. The Golgi apparatus is a stack of flattened sacs that is located near the nucleus of the cell.

It is responsible for processing and sorting proteins that have been made by the endoplasmic reticulum. The Golgi apparatus modifies proteins, packages them, and then ships them to their final destinations.

The Golgi apparatus has three main functions:

Modification: The Golgi apparatus modifies proteins by adding sugars, phosphates, and other molecules to them. This modification changes the properties of the proteins and makes them more functional.

Sorting: The Golgi apparatus sorts proteins into different vesicles. These vesicles are then transported to different parts of the cell, where the proteins are used.

Shipping: The Golgi apparatus ships proteins to different parts of the cell by fusing the vesicles with the cell membrane.
