Answer: The statement is TRUE.
Explanation:
The thin, yellowish milk which may appear at any time from late pregnancy to few days right after birth is known as Colostrum milk.
During pregnancy, progesterone and oestrogen cause the milk glands to develop in the mother's breast. Immediately after birth, the anterior lobe of the pituitary releases a hormone, prolactin, which stimulates milk production. When the baby suckles at the mother's nipples, the milk flows out.
This first yellowish milk known as colostrum, contains all the essential nutrients that a newly born baby needs. It also provides antibodies and immune cells that protect the infant from disease. The milk is rich in protein and fats than normal milk. It is the first immune system defense they receive after birth. Therefore the above statement about the first thin yellowish milk is TRUE.

3. The human body has devised an excellent method to keep the body pH under control. a. What principle underlies the constant pH of human blood, and how does the blood achieve this
: propels food through the digestive tract. : lines internal and external body surfaces. : conducts electrical impulses. : transports oxygen to the body tissues. : functions in secretion and absorption. : pumps blood. : stores fats and minerals.
Answer:
1. Muscle tissue.
2. Epithelial tissue.
3. Nervous tissue.
4. Connective tissue.
5. Epithelial tissue.
6. Muscle tissue.
7. Connective tissue.
Explanation:
A tissue can be defined as a group of cells that are structurally similar and in close proximity. Tissues are generally responsible for performing specific functions in living organisms such as humans, animals and plants. Therefore, tissues in living organisms function together as a unit.
There are four main types of tissues and these includes;
I. Connective tissue.
II. Epithelial tissue.
III. Muscle tissue.
IV. Nervous tissue.
In this scenario, the various types of tissues are matched with their functions as follows;
1. Muscle tissue: propels food through the digestive tract. It is mainly performed by peristalsis.
2. Epithelial tissue: lines internal and external body surfaces. It also referred to as epithelium and it comprises of sheets of cells.
3. Nervous tissue: conducts electrical impulses. A neural circuit can be defined as a group of neurons in the body of a living organism which are interconnected by synapses to perform specific functions when they're activated.
4. Connective tissue: transports oxygen to the body tissues predominantly through the Erythrocytes (red blood cells).
5. Epithelial tissue: functions in secretion and absorption.
6. Muscle tissue: pumps blood.
7. Connective tissue: stores fats and minerals.

You transform a population of cells with a transgene and isolate a cell line that has integrated the gene into its genome, but in which the gene is not expressed. Speculate as to what may be preventing the gene from being expressed. Describe two ways to test this possibility.
Answer:
The transgene could be silenced by: 1- epigenetic mechanisms (e.g., DNA methylation, histone deacetylation, etc.), and 2-the RNA interference (RNAi) pathway
Explanation:
Epigenetics refers to the heritable changes caused by the activation and deactivation of genes without changing the DNA sequence. Epigenetic mechanisms include 1-DNA methylation on cytosine residues, and 2-modifications on amino acids in the tails of histone proteins (e.g., methylation, acetylation, ribosylation, phosphorylation, etc). These two epigenetic mechanisms can modify DNA structure and thus alter the accessibility of transcription factors, thereby suppressing gene/transgene expression. Moreover, the RNA interference pathway (RNAi) is a naturally occurring mechanism capable of suppressing gene/transgene expression both at transcriptional and post-transcriptional levels. The RNAi mechanism is triggered by regulatory non-coding RNAs (ncRNAs) such as, among others, long non-coding RNAs (lncRNAs) and small ncRNAs (e.g., miRNAs, piRNAs, siRNAs, etc). In this case, for example, DNA methylation on promoter sequences could suppress transgene expression, thereby methods to measure DNA methylation can be used to test this possibility (e.g., bisulfite genomic sequencing). Moreover, miRNAs that bind to the messenger RNA of the transgene could also inhibit its expression by triggering the RNAi pathway (e.g., mRNA degradation), thereby methods to measure mRNA levels can be used to test this possibility (e.g., RT-PCR).
can increase biodiversity. (1 point)
O Changes in temperature
O Decreasing the food supply
O Limiting mates
O Protecting land
Biodiversity is the variety of life habiting the earth's ecosystem with numerous genetics and ecosystem levels. Protecting lands will increase biodiversity.
What is biodiversity?Biodiversity is the variety of living organisms living together in an area, that works together in an ecosystem to support life and maintain the population.
Biodiversity is affected by the temperature, food, reproduction rate, and habitat. Protecting the habitats will increase biodiversity.
Changes in temperature will affect biodiversity negatively, and decreasing food and reproduction ability will decrease the population of the biodiversity.
Therefore, option D. protecting lands can increase biodiversity.

6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.

Are mules an example of speciation? Why or why not?
Answer:
Hybrids are the offspring of two species. A mule is the hybrid offspring of a female horse and male donkey. Because mules are sterile, they are not classified as a distinct species. The biological species concept connects the idea of a species to the process of evolution.

In a good experimental design, the part of the experiment that is intentionally changed is the
A dependent variable.
B independent variable.
C constant
D control
Constants never change.
Controls typically don't change or they are done by standard means
(like in an experiment where you water plants with sodas, the plant you use water with is the control)
Dependent variables are the outcome of the experiment. This is the result of changing something.
Independent variables are what you are testing. A independent variable is something that is intentionally altered.
easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.
Living things_______in response to changer in there environment. 1.evolve. 2.fossils. 3.extinct. 4.species. Can some tell me which one it is?
Question 1 Negative Forcings: increase the amount of sea ice at the north pole for instance. O increase the growing season. increases the amount of energy in the Earth's budget. decrease the amount of energy in Earth's energy budget.
Answer:
increases the amount of energy in the Earth's budget.
Explanation:
Increase occurs in the amount of sea ice at the north pole leads to increases the amount of energy in the Earth's budget because this sea ice reflects the solar radiation back to space. Sea ice has a bright surface which causes 80 percent of the solar radiation reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface which leads the ocean to absorbs 90 percent of the sunlight which heat up the oceans, and increase in the temperature occurs causes more melting of ice so increasing sea ice is good for the earth.
