Answer:
Option D
explanation:
Gastric glands produce stomach acid and are part of the exocrine system. The exocrine system is a system of glands that produce and secrete substances directly into ducts that lead to the outside of the body, such as the skin or the digestive tract. Stomach acid is a digestive enzyme that is produced by the gastric glands and secreted into the stomach, where it helps to break down food. Therefore, the correct answer is option D, which states that gastric glands produce stomach acid and are part of the exocrine system.
In order to attract females, the male Bowerbird of Australia constructs elaborate structures called "bowers" on the forest floor. His bower is made from twigs, leaves, and moss, and is decorated with colorful ornaments such as feathers, pebbles, berries, and shells. If a female is sufficiently impressed with a bower, she will mate with the male who built it. This is an example of which of the five evolutionary forces
Answer:
non-random mating
Explanation:
The five different forces that influence species evolution are 1-non-random mating, 2-mutation, 3-gene flow, 4-genetic drift, and 5-natural selection. Non-random mating refers to phenotypic/behavioral differences that lead to preferential mating among individuals in a population (sexual selection). Mating behavior is a type of non-random mating pattern that includes mate choice (sexual selection) and increases reproductive fitness by increasing the chances of producing descendants (offspring).

what is the process when an embryo embeds itself into the endometrium
Answer:
Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes.
Explanation:
☁️ Answer ☁️
Implantation
1. Implantation is the process where the embryo attaches to the uterine lining (endometrium) and embeds itself into the tissue. This happens around Day 5 or so of the embryo’s development.

2. Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes. Without these changes implantation will not occur, and the embryo sloughs off during menstruation.

based on the information on the map where are the most stable ecosystems usually found?
The correct answer is C. Near the equator.
Explanation
The image shows a world map in which there is a horizontal black line in the middle that represents the equator line and some red areas. These areas are the most stable ecosystems in the world since due to their proximity to the equator the incidence of the sun's rays is more direct. Also, in these areas, there is no weather pattern defined by seasons, but climates are defined by altitude, that is, meters above sea level. Therefore, the correct answer is C. Near the equator.
Answer: c

A person touches a hot object and immediately moves her finger away from it. Which of the following structures is the first to receive an impulse triggered by the stimulus? and why
A Synapse
B Ventral root ganglion C Motor neuron
D Sensory neuron
E None of the above
The Sensory neuron is the structure that first receives an impulse triggered by the stimulus. Thus, the correct option is D.
What are Sensory neurons?Sensory neurons may be characterized as nerve cells that are activated by sensory input or external stimulus from the environment.
When a person touches a hot object and immediately moves her finger away from it. This is because sensory neurons are activated by an external stimulus, which is sent to the central nervous system of the body, and a motor response is sent out to the skeletal muscles that regulate this movement.
Therefore, the correct option for this question is D.

In how many revolutions can a bicycle
wheel of diameter 4.9 m cover a dis-
tance of 46.2 km?
Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

Biology 1 Post Lab Questions: 1. Which method appear · which method appeared to have the most dramatic denaturing effect on egg albumin? Why do you think this method had a greater effect?
Hello. You have not introduced the methods used to denature the egg albumin. However, the most efficient protein denaturation method is the heating method.
The denaturation of a protein, such as albumin, occurs when an element causes the complete destruction of the protein's three-dimensional structure, in a completely irreversible way. The best way to do this is through heat. In this way, through a heating method, the heat breaks the hydrogen bonds that promote the structure of the protein, leaving it completely denatured.

name and describe the process occurring in the nucleus wich results in the formation of an mRNA molecule.
Answer:
The correct answer is - transcription.
Explanation:
Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.
Transcription in prokaryotes is carried out in three stages.
Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.
Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.
Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.

What happens to species diversity WITHOUT Pisaster? *
Answer:
The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities. 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. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

Differentiate between deforestation and desertification
Answer: deforestation = cutting down of trees in large scale due to which it causes soil erosion. desertification = a process by which fertile land become desert ,typically as a result for drought, deforestation etc. Deforestation is defined as the cutting down or clearing of trees from a wooded area. ... If trees are removed, the area can become much warmer and drier, which may result in desertification, which is a transformation of once fertile land into desert.

Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?
Answer:
For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

Answer: Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte, and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state.Nuclear transfer is a form of cloning.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube
Answer:
Diffusion and active transport.
Explanation:
Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.
