Is duralumin a mineral, a rock, or neither?
Answer:
Duralumin is an aluminium alloy.
Explanation:
Duralumin is a kind of mineral.
What is Duralumin?There isn't a single chemical composition for duralumin because it is an alloy of copper, magnesium, manganese, as well as aluminum that can change based on its intended application. 4.4 percent copper, 1.5 percent magnesium, 0.6 percent manganese, and 93.5 percent aluminum make up a typical alloy.
What is mineral?A mineral would be an inorganic solid that forms in nature and have an organized atomic structure and a known chemical composition. Even while it may seem like a mouthful, if you break it down, it becomes clearer. Minerals have been created naturally. They are not human-made. They have inorganic, minerals.

The Wunderlich Farms Boer Goat has a 4 chambered stomach and chews it's cud to assist with digestion. What type of adaptions are these?
A. 4 chamber stomach = behavioral and chewing cud = internal structural
B. 4 chamber stomach = external structural and chewing cud = behavioral
C. 4 chamber stomach = internal structural and chewing cud = external structural
D. 4 chamber stomach = internal structural and chewing cud = behavioral
Answer:
The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"
Explanation:
Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.
All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.
In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.

Answer:
Morula.
Explanation:
A zygote is the product resulting from fertilization. During the journey of the zygote through the fallopian tubes, until its implantation in the uterus, it divides many times, thus going through different phases. From the 16 cells it is called a morula, this stage represents the set of cells from the division of the fertilized ovum, in the first stages of embryonic development. It represents an intermediate phase between the zygote and the blastocyst. The morula stage is characterized by the fact that the replicating cells are all the same size, and there is no differentiation of organs.

is biological control effective than chemical control of crop protection?
Answer:
No
Explanation:
There are different ways or methods of protecting crops from pest and disease infestation. Two of those ways as mentioned in this question are the chemical control and biological control. Biological control of crop protection involves the use of natural enemies of crop pests, which happens to be living or biotic organisms while chemical control entails the use of pesticides and herbicides to control crop pests and diseases.
Among these two methods, the chemical control is more effective because it yields instantaneous results and gets rid of pests and diseases faster. However, in terms of sustainability, the biological control method is more eco-friendly. Hence, based on this question, biological is not more effective than chemical control of crop protection.
Please list the order of organization within animals, beginning with the atom and ending with the organism. Describe each level of organization.
Answer:
Atom, molecule, cell, tissue, organ, organ system, and organism.
Explanation:
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the body's major organizational levels.
What are the levels of organization in animals?Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization that may be found in the body. These levels range in complexity from the simplest to the most sophisticated.
Cellular level is key. A cell is the smallest self-replicating unit of life. All cells share a few cells, despite differences in design and capacity. Cells contain nucleic acids (DNA and RNA), cytoplasm, and a lipid-based film. Cells have organelles in their cytoplasm that perform distinct functions.
Tissues are clusters of related cells that function together. Connective tissues provide organs shape and structure. Muscle cells contract to allow movement. Epithelial tissues cover organs, skin, and the stomach. Specialized cells in nervous tissue, the spinal cord, and the brain transform information using electrochemical impulses.
Organs are structures made of tissues that perform biological activities. Organs have tissues. Organs combine tissues to perform a certain purpose. Size and complexity of organs vary tremendously. Organs include the heart, lungs, and brain. The next level, organism level, is formed of different organs to maintain the body.

The deltoid muscle can effectively contract through its entire ROM because of the upward rotation of the scapula, which serves to maintain tension in the deltoid muscle. If the deltoid loses tension, it becomes
Answer:
Actively insufficient
Explanation:
The deltoid is a muscle attached by tendons to the bones localized on the top of the shoulder (clavicle, scapula and humerus). The amount of force generated by a multi-joint muscle decreases as the muscle moves the joints simultaneously. A multi-joint muscle becomes actively insufficient when it shortens over both joints simultaneously and it no longer has the ability to develop an effective tension. Moreover, a muscle is passively insufficient when it can't be stretched to its fullest length across multiple joints simultaneously.

Energy is released from ATP when a fourth phosphate is added to the molecule the last phosphate bond is broken.
What is ATP?ATP, sometimes referred to as adenosine triphosphate, is a chemical that transports energy inside of cells. It is produced as a byproduct of photophosphorylation, which adds a phosphate group to a molecule using light energy, cellular respiration, and fermentation. It serves as the primary energy currency of the cell.
All forms of life utilize ATP. In addition to being used as an energy source, it is also integrated into deoxyribonucleic acid (DNA) during DNA synthesis and utilized in signal transduction pathways for cell communication.
Therefore, Energy is released from ATP when a fourth phosphate is added to the molecule the last phosphate bond is broken.

The cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.
What is the S phase in the cell cycle?The cell cycle has different phases, and each phase is specific for a particular function, such as the G1 phase, which is the first growth phase. In the G1 phase, the growth of the cell takes place, such as the new protein synthesis, and then the cell enters the S phase, in which the DNA replicates and a copy is made.
Hence, the cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.

How would you describe the interior of the lungs?
Explanation:
The interior of the lungs is made up of spongy tissues containing many capillaries and around 30 million tiny sacs known as alveoli.
The alveoli are cup-shaped structures found at the end of the terminal bronchioles and surrounded by capillaries.
Answer:
It's spongy and air filled sort of.
Explanation:
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.
