4. Describe an observation you made today and an inference you can make from that observation.
Answers
Answer:
my my teacher gives my class and I a mystery box for us to observe what's inside that box it was closed, as we was trying to know what's inside that box we were looking and thinking what does it sounds like, but my friend next to me says it sounds like a stapler and my other friend said it's not very heavy, as we were we said we could take another box just like that identified box and put a stapler since it sounds like a stapler and it's not that heavy as we know staplers are not that heavy. well we did that we check and our activity shows that the mystery box it slides and appear to be flat and all the box it slides in appear to be flat so that's the same thing as our box and the mystery box and we were looking at how does it sound when we close the box and everything we were checking how does it sound as we are observed that the mystery box it makes a metallic song when it strikes the side of the box an hour box the stapler makes a thudding sound when it strikes the side of the box and we also checked if the mass of the box was the same but it wasn't the mystery box was 270 g and our box was much more heavier which is 410 g so we were checking what was the really wrong thing we was checking and checking is like what should we do next, and we did in for the things in the box had to be different because our observation of the two boxes are different, and we observed yes things are different of course.
and there's a picture with the observation chart I will be showing it's above take a look and you will be have more understanding and knowledge about the really topic I am talking about thank you.

As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis
Answers
Answer: Is a result of genetics and environmental factors.
Explanation:
Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.
A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.
Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.
So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

How do organisms in the rainforest compete for biotic and abiotic factors? (Emergent layer, canopy layer, understory, forest floor?) In the ecosystem. Giving brainliest.
Answers
Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.
Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.
Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.

Assume that you are a genetic counselor and that a couple seeks genetic counseling from you. Both the man and the woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this couple will produce a child with a genetic syndrome as the result of crossing over within the pericentric inversion
Answers
Answer:
50%
Explanation:
An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.
