The correct steps of endochondral ossification is:
A periosteal bone collar develops.spongy bone and the medullary cavity form in the diaphysis.The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.The spongy bone forms in epiphysis.Which bones grow by endochondral ossification?Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.
Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.

An angle measures 176 more than the measure of its of its supplementary angle.what is the measure of each
angle
Based on the definition of supplementary angles, the angles are: 2° and 178°.
What are Supplementary Angles?Angles that are supplementary have a sum that equals 180 degrees.
Let the measure of the supplement be x.
The other angle would be: (x + 176)
Therefore, we would have:
x + (x + 176) = 180
2x + 176 = 180
2x = 180 - 176
2x = 4
x = 2
One of the angles is, 2°
Second angle = x + 176 = 2 + 176 = 178°

happen to the barred owl
population in that ecosystem?
A. The barred owl population in that ecosystem would stay the same size.
B. The size of the barred owl population in that ecosystem would decrease.
C. There would be no change in the barred
owl population.
D. The amount of barred owls the ecosystem can support would increase.
The size of the barred owl population in that ecosystem would decrease.
Reduced biodiversity, or the variety and richness of various kinds of animals and plants in a given setting, is the main consequence of habitat degradation. An animal's population rapidly declines as it draws closer to extinction when it loses the habitat or natural home that it requires to survive.A proportional drop in the number of animals inhabiting a given landscape is predicted to result from habitat destruction. One might anticipate a drop in animal abundance of 50%, for instance, if 50% of a forest environment that supports a big population of an animal is destroyed.similarly, If all of the large, dead trees were removed from the ecosystem, The size of the barred owl population in that ecosystem would decrease.learn more about ecosystem here:

rainforest:
A. Experience some of the most
fertile soil in the world.
B. Help each other to grow and

C. Are constantly competing for
scarce water resources.
D. Are numerous and in constant
competition for sunlight.
The rainforest is one of the most diverse biomes. Options A and D. Experience some of the most fertile soil in the world. Are numerous and in constant competition for sunlight.
What si the tropical rainforest?The tropical rainforest is a biome is located near the equator, where precipitations are abundant and the average temperature is elevated most of the year.
As a result of the climatic conditions, this biome gives shelter to a huge number of living organisms. The canopy structure provides many refuges for plants and animals and is an important source of food. It also favors interactions between species.
There are different plant species, such as epiphytes, lianas, stranglers, aerial-rooted pants, and tabular-rooted plants, among other vegetation forms.
Fanerophic species dominate this biome. Evergreen tall trees might reach up to 50 meters in height. They develop dense foliation and branches, becoming a refuge and source of food for many species.
Vegetation does not need to develop strategies for surviving the dry season. Instead, they need to develop strategies for competing for light and nutrients.
Since vegetation is very dense, woody species grow in height looking to get greater sun radiation. Competition for sunlight is quite significant, generating different strata canopy at varying levels in the forest.
Abundant vegetation and other factors such as temperature, precipitation, and natural cycles create one of the most fertile soils favoring the growth and development of many species.
According to this framework, the correct options are A and D. Experience some of the most fertile soil in the world. Are numerous and in constant competition for sunlight.

explain in steps how a tree trunk gets wider
Answer:
The first thing that determines the thickness of a tree trunk is the species. Some kinds of trees just naturally have a different trunk thickness than others.
The second thing might be the environment. A tree that is experiencing all factors - sun, water, soil, minerals - at an optimum level is going to grow faster, taller, stronger, and thicker than the same species in a less-optimum environment.
A third factor is time. As time passes, the tree trunk increases in diameter - thus a tree that is 50 years old will have a much thicker trunk than one that is 5 year old.
And, in case you’re wondering why or how tree trunks increase in thickness at all, there is a thin layer of cells all around the trunk of a tree, like a sheet that lives under the bark. This layer is called the cambium layer which makes new living tissue for the tree (called phloem and xylem) every year. As the year’s growth comes to an end, the living tissue dies and is pushed outward to appear as bark by the new year’s sheet of cambium cells, which is bigger than the previous year’s - hence, the increase in diameter of the tree every year.

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.
DNA replicationThe biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:
cell division during tissue development and repair, and it also guarantees that each new cell gets a copy of the DNA.A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.
These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

which of these should be reportable reasons to protect public health?
a) Skin cancer
b) Heart disease
c) HIV
d) Diabetes
Among the following HIV should be reportable reasons to protect public health.
HIV impairs the body's defenses against infections and leads to AIDS. Contact with contaminated blood, or fluids might result in the virus being spread. Flu-like symptoms including fever, sore throat, and exhaustion might appear a few weeks after HIV infection. Until AIDS develops, the illness is typically asymptomatic. Fatigue, fever, night sweats, and weight loss are a few of the signs and symptoms of AIDS. Despite the fact that there is no known treatment for AIDS, diligent adherence to anti-retroviral therapy (ART) can significantly decrease the disease's progression, avoid complications and secondary infections, and lengthen life. One of the primary tactics used in the prevention and control of HIV/AIDS around the world is the dissemination of information and awareness about HIV.

Other things being equal, what is a potential disadvantage of an enzyme having a very high affinity for its substrate?.
Since the ES complex would be in a "energy trough," the activation energy for the transition state would be quite high.
What is enzyme?Tight enzyme substrate binding will lower the reaction's forward rate constant.A forward reaction's activation energy will increase when an enzyme's affinity for its substrate is high.Because the enzyme-substrate complex will be located in a deep energy well, it will be more stable.In contrast to the situation where the substrate-enzyme binding is weaker, a tight binding of the substrate to the enzyme will alter the amounts of free substrate and free enzyme. This little modification won't have much of an impact on the reaction kinetics because the substrate concentration is often higher than the enzyme concentration.It is unlikely that tight binding would result in the active site being altered. Since the enzyme is significantly bigger than the substrate, it is unlikely that it will change shape.Learn more about enzyme here:
