Which statement correctly describes a chemical reaction?
A. Reactants come out of a reaction.
B. Energy is always released.
C. Bonds between atoms break and reform.
D. Products go into a reaction.
Answer:
C). Bonds between atoms break and reform.
Explanation:
A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, option C is the correct answer.

The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.

Which situation is most likely to result in a mutation that is passed on to an offspring?
A- ultraviolet radiation causing skin cancer
B- a longtime smoker developing cancer in the lungs
C- exposure to a chemical that affect cell formation
D- exposure to a chemical that affects the nervous system
Answer:
C- exposure to a chemical that affect cell formation
Explanation:
Hope this helps
The situation that is most likely to result in a mutation that is passed on to an offspring is exposure to a chemical that affects cell formation. The correct option is C.
What is mutation?A mutation is changing or modification in the nucleic acid or DNA sequence of a person. This is a natural process that occurs due to mutagens.
Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. An example is an aneuploidy is a condition of the presence of more or less number of chromosomes than normal. For example, there are 45 or 47 chromosomes are present.
There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.
Therefore, the correct option is C. exposure to a chemical that modifies cell formation.

When your ad appeals to the fears of a consumer, which advertising technique are you using?
humans have 46 chromosomes. guinea pigs have 64 chromosomes. kiwis have 174 chromosomes. bananas have 33 chromosomes. strawberries has 16 chromosomes. what connection exists between the numbers of chromosomes and the complexity of an organism? explain your thinking
Answer:
There is no correlation/connection between number of chromosomes and complexity of an organism.
Explanation:
If the number of chromosomes determined the complexity of an organism, we could say that the kiwi in this problem is more complex than the human, however, this is not true. A chromosome is like a container for the genetic material (genes) of an organism, it doesn't matter how many containers there are, but rather what's inside the containers that determine genotype and phenotype.
Answer:
Not much.
Explanation:
Considering the fact that banannas have like half of the chromosomes that a living animal has, and the fact that an animal somehow has more chromosomes than a human, leads me to believe there is little to no correlation with the amount of chromosomes someone has and their complexity.

Some insect species are resistant to pesticides. Which statement BEST explains this phenomenon? Natural selection resulted in an unfavorable variation for the insects. Because their survival depended on it, the insects developed variations that made them resistant to poisons. Random variation in the population led to a population with a favorable adaptation. Some of the insects became instantly immune when the poisons were introduced into their environment
Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-de novo mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).

Which of the following best describes homeostasis? the state of maintaining a stable internal environment despite changing external conditions the state of maintaining a stable internal environment due to electrical impulses the state of maintaining a stable internal environment due to chemical signals the state of maintaining a stable internal environment when the external conditions are constant
Answer:
the state of maintaining a stable internal environment despite changing external conditions
Explanation:
homeostasis is all about regulating, whether it be regulating body temperature through shivering, regulating body water levels, etc..
The best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions." Homeostasis is a vital physiological process that helps to maintain the internal environment of an organism.
What is homeostasis?To achieve homeostasis, the body uses various physiological and biochemical mechanisms to monitor and respond to changes in the external environment. For example, if the external temperature becomes too high, the body will respond by sweating to cool down and maintain a stable internal temperature. Similarly, if the blood pH becomes too acidic, the body will respond by increasing the excretion of hydrogen ions to restore a more neutral pH.
Hence, the best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions."

Complete the following statements. Ions are necessary to activate the binding sites on the actin filaments. The molecule is required each time the myosin head detaches from one site and reattaches to another.
Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
What do you mean by actin filaments?It is microfilaments that are responsible for cell shape and cellular movements.
The calcium ions are released when there is depolarization of the sarcomere occurs. They then bind to troponin and restructure the complex that is exposing the binding sites to the myosin head.
The cellular importance of the motor proteins is ATP-dependent which forces the impulse to actin filaments, and then the myosin head detaches from the old binding sites of actin.
Therefore, Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.

The data indicate the populations of mammals in the Florida Everglades in different years over the past two decades. The Burmese python, a non-native species, was introduced to Florida as an exotic pet. After Hurricane Andrew hit Florida in 1992, many pet owners lost track of their non-native snakes. The biodiversity of the Everglades has decreased since then. According to the data, what hypothesis is best supported with regard to Burmese pythons and Florida Everglade biodiversity?
Answer:
The correct hypothesis would be - C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Explanation:
Burmese pythons are the invasive species in this new region as they originally found in South Africa, and also one of the largest snakes so they lack natural predators in this new setting or region.
These snakes depend on both types of food which means they are omnivorous and eat both herbivore and carnivores prey.
Thus, the correct answer is - Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Answer:
C. Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades
