Zora and Neil are learning about succession in their biology class. They decide to do their midterm project on the succession that occurred after the dinosaurs went extinct from the ice age. Neil says that the ecosystems that arose after the ice age are an example of primary succession, but Zora thinks they are an example of secondary succession. Who is correct?
Neil, because those ecosystems will be first emerging after the ice age.
Neil, because plants were the first lifeforms to take place in those ecosystems.
Zora, because secondary succession occurs when there is a catastrophic destruction to a previous ecosystem.
Zora, because secondary succession occurs when a species of animals becomes extinct.
Zora is correct because secondary succession occurs when there is a catastrophic destruction to a previous ecosystem.
What is Secondary succession?This usually follows a primary succession and occurs when there is existing presence of life forms.
This is caused by disruptions in the ecosystem such as wildfires, glaciers etc which removes only part of the soil in the area.

4. Which is a
consequence of global warming?
O rise in number of glaciers
O rise in number of ice-capped mountains
O rise in sea level
O rise in fossil fuels
Answer:
3. Rise in sea level
Explanation:
As the glaciers melt the water from the melted glaciers causes the sea to rise since more water is being added. Not answer 1 or 2 because ice melts as it gets warmer.
Which of these has the highest BTU content when burned?

Marsupials are found in North America and Australia, but they would not have been able to swim across the ocean. According to scientists, how did this group of organisms come to live on two separate continents
Marsupials come to live on two separate continents when both continents were attached to each other.
What is the reason for the presence of Marsupials?Marsupials are the group of organisms that come to live on two separate continents a long time ago when both continents i.e. North America and Australia were joined or attached to each other. The supercontinent named Pangea began to break apart about 200 million years ago which results in the formation of continents.
Before this is broken, the Marsupials move to the Australian part from the North American part so we can conclude that Marsupials come to live on two separate continents when both the continents were attached to each other.

A student completed an experiment investigating the response of tomato plants to gravity and created the table below. What can you conclude from the observations? A table showing the observations in an experiment investigating how plants respond to gravity. The top row shows observations from a plant grown upright in a pot. The observations are as follows: the stem grew straight upward on day one, straight upward on day two, straight upward on day three, straight upward on day four, and straight upward on day five. The bottom row shows observations from the plant grown in a pot on its side. The observations are as follows: the stem grew straight outward on day one, it started to bend on day two, more bent on day three, bent like the letter L on day four, and continued to grow in a bent fashion on day five. Gravity does not affect the growth of a plant. Gravity has no effect on the plant grown on its side. The stem of a plant will grow downward with gravity. The stem of a plant will grow upward against gravity.
Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
What is negative gravitropism?Negative gravitropism occurs when shoots develop in the opposite direction of gravity toward sunlight.
Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
Thus, the given experiment shows negative gravitropism.

Explanation:
The actions that can be performed by RNA are it can carry genetic information from one part of the DNA to another, and it can block the process of transcription. The correct options are A and C.
What is RNA?All living cells contain ribonucleic acid (abbreviated RNA), a nucleic acid with properties comparable to those of DNA. However, RNA is often single-stranded, unlike DNA.
Instead of the deoxyribose found in DNA, the backbone of an RNA molecule is formed of alternating phosphate groups and sugar ribose.
RNA does the translation process which is after the transcription, so that why it blocks transcription

1.Identify the role of endocrine glands in growth/development, and in regulation of metabolism.
2. Compare hormonal and nervous control of homeostasis
3. Classify the mechanisms through which hormones affect target cells, the major chemical classifications of hormones, and the principles of positive and negative feedback
In this question we are going to answer a series of questions about the human endocrine system, hormone release and homeostasis.
What is human endocrine system, hormone release and homeostasis?1. Endocrine glands produce hormones and release them directly into the bloodstream.
Hormones are the products of secretion from the endocrine glands. They control various activities in the human body, hence the importance of these glands.
2. It is through the feedback mechanism that, for example, the regulation of hormone secretion and the control of temperature and blood pressure occur.
Thanks to this control, it is possible to guarantee the harmony of the systems and, consequently, the homeostasis (balance of the internal environment).
3. Hormones can be divided into four groups, based on their chemical structure,form of synthesis and storage, solubility, half-life, form of transport, receptors on cell and mechanism of action:
PeptidesSteroidsAmines and Eicosanoids.Both positive and negative feedback are extremely important for our body to function properly. However, these two mechanisms have differences. In negative feedback, the body produces a response that reduces the initial stimulus, while in positive feedback, the response reinforces the stimulus.

A geneticist is studying a disease trying to determine how its inherited. DNA testing was completed on three generations of a family and a pedigree chart below was created based on the results fell in shape means that the person has the disease a Hatfield shape mean that the person carries the gene for the disease but does not have the disease males are often affected then females females tend to be carriers what term is the type of inheritance is this
Answer:
X-linked recessive inheritance
Explanation:
Since the disease is primarily present in males vs females, it is a s.ex linked disease.
In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.
Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.
