Explanation:
in yeast that has been genetically modified to be able to produce spider silk, the ________ is joined with the ________ .
A transgenic organism is an organism whose genome (DNA) has been altered by recombinant genetic engineering techniques. These techniques can be used to transfer exogenous genes within transgenic species.
In yeast that has been genetically modified to be able to produce spider silk, the spider silk CODING SEQUENCE is joined with the yeast REGULATORY SEQUENCE.In this case, transgenic yeast has the spider silk coding gene sequence (i.e., the exons) that encodes for the spider silk protein, whereas a regulatory gene sequence (e.g., a promoter gene sequence) from yeast have been preserved in order to regulate the expression of the target exogenous gene.The most important genetic engineering techniques used to create transgenic animals include DNA microinjection and retrovirus-mediated gene transfer.Learn more in:

12.What is an invasive species?
A native species which are added to an area
A keystone species in an environment
A non-native species added to an area
Answer:
An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.
To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem
An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

without making any other adjustments the _____ can be increased by focusing properly.
Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.
A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.
The brightfield microscope is widely used in cellular biology and microbiological laboratories.
The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).
This maximum value can be reached by changing the objective lens.

Why does the brain of mammals keep track of the temperature of the skin and the blood?
Answer:
The thermoregulatory center in this gland regulates heat loss and production. This center is influenced by nerve impulses from receptors near the skin and the temperature of the blood flowing through it. When the environment is warm or hot, there are a variety of ways mammals stay cool..
Explanation:
Hope it helps you..
Y-your welcome in advance..
(;ŏ﹏ŏ)(ㆁωㆁ)
The brain of mammals keeps track of the temperature of the skin and the blood so that they can regulate the cells and maintain homeostasis in the body relative to the outer environment.
What is the importance of homeostasis in the body?The body's homeostasis should always be maintained in order to keep the cells and organs active and able to perform their functions. Because the brain has different control centers, it keeps track of the skin and blood temperature because the brain can release different hormones depending on the situation. The lipid composition and arrangements of the cells change in the summer and the winter, and all these are possible due to the brain sending signals to cells.
Hence, the brain of mammals keeps track of the temperature of the skin and the blood so that it can regulate the cells and maintain homeostasis in the body relative to the outer environment.

What do people with Glycogen Disorder Disorder need to do in order to maintain a normal blood glucose?
the muscles and organs need a certain level of glucose in the blood to work properly. When the body is missing an enzyme or has a flawed enzyme and is not able to use glycogen the right way, it leads to a condition called glycogen storage disease (GSD). Many different enzymes are used by the body to process glycogen.

Mecayla harvests oysters from the shallow waters of the marsh near her home. She eats the shellfish almost every day. Her brother Kendis dislikes oysters but eats local predator fish from the river three times a week. Recent water quality tests show moderate levels of heavy metals in the river and marsh. What is the most likely result of this pollutant on Mecayla and Kendis if they maintain the same diet?
Mecayla will get sick first because she eats oysters every day.
Kendis will get sick first because of less bioaccumulation.
Biomagnification will cause Kendis to become ill first.
Bioaccumulation will cause Mecayla to become ill first.
Answer: Biomagnification will cause Kendis to become ill first.
Explanation: This answer is correct because Kendis is eating the predator fish and Mecayla is only eating some oysters from the shallow water. Biomagnification causes the concentration of toxins, specifically in the predator fish, therefore Kendis will become ill first.
Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.
