Janelle was telling her mom about a dream where she was being chased by wolves. She said she ran and ran and when she woke up, her heart was beating rapidly, and she was very tired.
Which gland had secreted a hormone that caused her body to respond in this way?
A) the thyroid
B) the thymus
C) the pancreas
D) the adrenal gland
The gland that secreted the hormone that made Janelle respond as such would be the adrenal gland.
The adrenal glandThe adrenal gland is responsible for the secretion of hormones such as cortisol, adrenaline, and aldosterone. These hormones have a wide variety of functions that help maintain the normal body system
Of particular importance is adrenaline in the fight or flight response of humans. It makes major blood vessels contract and redirects blood to the heart - thus causing the heart to beat faster.
Hence, Jenelle's response would have been due to the adrenal gland producing the adrenaline hormone.

Which structures are similar in function, but do not indicate that the organisms are related?
analogous structures
homologous structures
vestigial structures
transitional structure
Answer:
A
Explanation:
analogous structures
Analogous structures are similar in function but do not necessarily suggest that the organisms are related.
What are analogous structures?The term “analogous” is used to describe biological structures that have similar or analogous functions but are not of the same evolutionary lineage. This means that the same biological structures are used by the same species for the same purposes, but the species are from different evolutionary origins. This type of evolution is called convergent evolution.
For example, similar structures of different species might have similar or equivalent functions, even though they originated from a different evolutionary point of view.
The wings of birds and insects are similar organs. Both birds and insects have wings that allow them to fly. However, their wings come from different ancestors. This is an example of analogous structure.

What are the processes involved in cellular division?
Answer:
I hope this helps!!
Explanation:
The existence and perpetuation of life depend on the functioning of cells and their divisions. There are two important processes of cell division, which are inextricably linked with each other to maintain the progress of life. These processes are Mitosis and Meiosis.
After fertilization, when a sperm cell and an egg cell unite to form a new organism, it is expected to carry a double number of chromosomes because both the parents contribute their whole number of chromosomes as appropriate for the respective species. But the process of meiosis prevents the doubling of the chromosomes.
It reduces the total number of chromosomes in half so that the offspring (newly formed cell) can retain the same number of chromosomes as the parents. On the other hand, mitosis facilitates in forming of two daughter cells from a single cell where each new cell resembles the parent cell in every respect. Unlike meiosis, mitosis involves duplithe cation of chromosomal pairs, which is essential for cellular reproduction, especially during growth.
The Mechanism of Mitosis:
A specific process is required for forming two daughter cells out of a mother cell. This process is known as mitosis and it is usually divided into four stages, prophase, metaphase, anaphase, and, telophase. In some cases, it is convenient to designate the transition from prophase to metaphase by the name of prometaphase. However, the whole process of the cycle of mitosis is a continuous one.
1. Prophase:
At the beginning of the prophase stage, the cell prepares itself to divide the chromosomes. It is the resting stage when the nucleus becomes a little larger. It also involves the condensation of the previously diffuse, invisible, or dispersed threads into visible chromosomes.
Each chromosome is optically double, which is composed of two identical and closely parallel strands or chromatids lying throughout their length. A chromosome bears a constriction or a narrow region of attachment to the spindle, which is called a centromere.
Constrictions other than the centromere are sometimes called ‘secondary constrictions’.At prophase s,tage the centromere and secondary constrictions look alike, but by metaphase, this distinction is clear because they develop entirely different relations to the spindle.
In this stage (prophase) the outlines of the chromatids present a slightly irregular woolly or hairy appearance. They do not, in general, show a series of granules (chromo-meres) as are seen at the meiotic prophase, and probably this is a real difference between the two. By the end of the prophase, the woolly appearance almost disappears and a smooth outline is visible.
2. Premetaphase:
At the end of the prophase, the nuclear membrane usually disappears and this stage may be defined as the period of spindle formation. During this stage, the chromosomes give an impression of struggling and pushing among themselves too to reach the equator of the developing spindle. The spindle is relatively a solid gelatinous body. It is composed almost entirely of protein with a very small amount of RNA.
The centrosome seems to act as an organizer of the spindle. The centrosome is the differentiated region of cytoplasm containing centriole, which is a minute granule present just outside the nuclear membrane. After the disappearance of the nuclear membrane, the centriole is doubled and the two centrioles move apart from each other to form the poles of the spindle.
The spindle fibers are probably bundles of protein molecules. A distinction may be made between continuous fibers and chromosomal fibers. The continuous fibers run from pole to pole whereas the chromosomal fibers connect the centromeres to the poles.
In the case of bipolar spindles, the equatorial plane is located perpendicular to the long axis, which is the midway between the poles. As the prometaphase proceeds, the chromosomes arrange themselves with their centromeres, on the equatorial plane of the spindle. It is the most dynamic stage which gives rise to a relatively static Metaphase.
Explain how the development of agriculture and the green revolution both affected humans. then explain how agriculture and the green revolution affected the environment. please be detailed in your response and write in complete sentences for full credit.
Answer:
The Green Revolution involved the widespread use of chemicals in agriculture that had adverse environmental impacts. The interrelationships between water resources, erosion, pesticides and fertilizers, deforestation, population pressure, and biodiversity, and farmers are individually addressed.
Explanation:
The development of agriculture and the green revolution affected humans by increasing food production. However, it also led to environmental degradation.
What is green revolution?The development of agriculture provided humans with a stable food supply and allowed for the growth of civilizations. It also led to the domestication of animals and the creation of farming communities. The Green Revolution, which began in the mid-20th century, involved the development and implementation of new agricultural technologies and increased the productivity of crops, leading to increased food production and economic growth in many countries.
However, the use of pesticides and fertilizers in agriculture has had negative impacts on the environment, including soil degradation, water pollution, and loss of biodiversity. The Green Revolution also resulted in the increased use of mechanized farming, which led to the loss of natural habitats and the displacement of wildlife.
Climate change caused by agricultural practices, such as deforestation, and the use of fossil fuels in farming, has also had a significant impact on the environment.

Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.
