Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.

Burrowing owls sometimes build their nests in holes that were dug by prairie dogs, coyotes, or badgers and have been since abandoned. They sometimes line the nests with cattle or horse dung. Why
Answer:
To avoid extreme temperature and keep away predators.
Explanation:
Burrowing owls sometimes line the nests with cattle or horse dung in order to avoid extreme temperature. The cattle dung protect the Burrowing owls from extreme temperature of the surrounding so they make nests close to these cattle dung. These dung has many insects which is a food of Burrowing owls and this cattle dung also keep predators away from Burrowing owls.
What is the function of RNA in a cell?

Explanation:
Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.
Answer:
The correct answer is c. an efficient system for conducting water and minerals.
Explanation:
Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.

25. A cell has 20 amino acids. How many molecules of tRNA are in the cell?
1. Four
2. Three
3. More than 20
4. At least twenty
5. Fifteen
6. I do not know.
Answer:
I think no 3 will be the answer.
In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.
What is tRNA?Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.
There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.
Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.
Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.

High Altitude Living Quick Check
Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.
What do you mean by Adaptations?
Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.
Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.
Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

a. a flat plain
b. a trench
c. a mid-ocean ridge
d. a continental shelf
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Where is the diaphragm located in relation to the lungs?
a) inferior
b) medial
c) superior
{ Relating to a crash course video called: Respiratory System Crash Course}
[any information would be very much appreciated! thank you :D]
Answer:
A. Inferior
Explanation:
If you're not familiar with anatomical terms, a quick summarization would be:
-Inferior: below
-Superior: above
-Medial: towards the midline of the body
Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.
I hope this answer and explanation helped you understand this topic a little bit more!
The diaphragm is located in inferior to lungs.
What is diaphragm ?
In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.
It is the primary respiratory muscle.
The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.
Vacuum is created due to contraction, which pulls air into the lungs.
Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.
So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

Explanation:
Maintaining high global biodiversity is important to provide ecosystem services to humans. Describe one cultural ecosystem service provided by diverse ecosystems.
Answer:
Ecosystem services of provision or supply
Explanation:
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.
Support:Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:
→ Soil formation
→ Photosynthesis
→ Primary production
→ Nutrients cycles
→ Water cycle
Under certain circumstances, regulation services can also be considered support services.
Support service affects human beings indirectly, or direct but causing an effect in a long-term period.
