Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

PlLEASE HELP ME> I NEED THIS ANSWER RIGHT NOW. The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these oxygen-dependent organisms could no longer survive. How would you modify this investigation of the pond organisms to determine if the algal bloom really was the cause of the bass and crayfish die-offs?
Answer:
bacteria blooms and decreased underwater photosynthesis causes hypoxia, killing the fish. c. floating algae die, increasing sunlight penetration and heating the water. ... This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water

Explain why a topographic map has a key.
Topographic maps represent the locations of geographical features, such as hills and valleys.
What do you mean by topographic maps?Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines.
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes.

All of these are the questions that involves ethical considerations because the method used in these questions are not doing naturally. Vitro fertilization is the fusion of woman's egg with the sperm of male outside the uterus of women which is unethical. Testing of unborn children in the womb for genetic disorders and producing genetically modify plants are also unethical because it does not occur naturally. It occurs due to intervention of humans in God's creation.
100 points (50 each) How do workers decide when to set a controlled burn, and how do they know if they have been successful?
Answer:
It is very important to have the latest and most updated weather conditions available before starting the burn. Relative humidity is an important factor to consider when planning a controlled burn. If the relative humidity is below 50%, the dryness of the grass is prone to causing very hot fires
Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a relationship.
Answer:
Parasitism
Explanation:
This is because parasitism is a type of relationship that exist between organisms where one which is the predator feed on the prey thereby causing harm or injury or death to the prey. In the question, small frogs are the predators and insects are the prey, therefore the predators cause harm to the prey, meaning they only benefits from the farm they cause the prey.

All of the following are used by taxonomists to create evolutionary links between species EXCEPT
Select one:
a. analogous structures
b. the fossil record
c. molecular data
d. vestigial structures
The fossil record, molecular data and vestigial structure would help taxonomists to create evolutionary links between species except analogous structures.
What do you mean by fossil record?"A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order."What is molecular data?"Molecules such as sequence of DNA used in studies of intra-specific variation and studies of similarity among species."What is vestigial structure?"Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures."What do you mean by taxonomists?"Taxonomists are professionals who specialize in classifying and sorting information based on similar characteristics and patterns."What are analogous structures?The structure of different species performing similar function but are from different origin (do not have common ancestor).The fossil record, molecular data and vestigial structure all would help taxonomists to find evolutionary links between species where through analogous structures no links would be created.
Hence, the correct option is a. analogous structures.

Which of the following is not a health risk associated with ozone?
A) skin cancer
B) cataracts
C) obesity
D) respiratory illneses
Answer:
obesity
Explanation:
The following that is not a health risk associated with ozone is obesity. The correct option is C.
What is ozone?Ozone is a trioxygen inorganic molecule that is of pale blue color. The ozone layer is present in the stratosphere of the atmosphere. It absorbs the UV rays coming from the sun. Thus, it is a protective layer that saves from UV rays.
UV rays are harmful rays that affect health. It creates skin problems and many other health problems. So the ozone layer protects us from UC radiation, it acts as a shield.
Obesity is a condition in which the body becomes fat. It happens with the accumulation of fat in the body. This does not occur with UV rays. It occurs due to food. So this will not be a health risk associated with ozone.
Thus, the correct option is C. obesity.

Maintaining homeostasis keeps the internal environment in the body functioning properly. Many organ systems work together and maintain energy homeostasis. The digestive system is concerned with processing the food that we take in to provide essential nutrients to the rest of the body. Which of these body systems works most directly with the digestive system in the absorption of nutrients?
A) urinary system
B) endocrine system
C) respiratory system
D) cardiovascular system
Answer:
D
Explanation:
However, the organ systems also work together to help the body maintain homeostasis. For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure.
