explain two characteristics of arthropods that makes them most successful of vertebrates
Answer:
1. Exoskeleton
2. Jointed appendages
Please find the explanation of the mentioned characteristics below
Explanation:
Arthropods are a group of animals that lack backbones i.e invertebrates but possess jointed legs. Arthropods as their name implies all belong to a large phylum called ARTHROPODA. They include insects, crustaceans etc. Due to their large number among other animal species, their outstanding variety etc, they are considered the MOST SUCCESSFUL animals.
This success of arthropods can be attributed to the characteristics they possess. Two of them are:
- EXOSKELETON: The outside skeleton possessed by members of these phylum supports their body, movement and general protection.
- JOINTED LEGS/APPENDAGES: Arthropods are virtually the only set of organisms that have jointed appendages giving them the adaptational ability to live and thrive in almost every habitat, if not all.
this is a trait passed down to us from our parents or other relatives. it is passed down through genes
Answer:
Inherited traits are the ones which have passed on from the parents to the children and can go on passing to the coming future generations as well. Traits are the physical characteristics expressed when specific allele of specific gene is present.
Determine which of the following choices is the best match for the questions that follow: A. Whole-organism Vaccine B. Subunit Vaccine C. Toxoid Vaccine D. Experimental Vaccine
Answer:
Experimental Vaccine Herpes Vaccine = D
Attenuated = B
Purified macromolecule Vaccine = B
Recombinant-Vector Vaccine = A
Inactivated or Killed = C
Diphtheria Vaccine = A
Explanation:
A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.
Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).
The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses
Directions: Select the correct term or terms from the table. Different organisms have different traits, or characteristics. Some of an organism's traits are inherited from the organism's parents, while other traits are more strongly influenced by the organism's environment. Among most animals, which of the following traits are usually directly determined by genes inherited from the organism's parents? sex body weight knowledge blood type
Answer:
The correct answer is - sex and blood type.
Explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.

Reverse transcriptase is a useful enzyme to have when?
Answer:
Reverse Transcriptase (RT) is essential for HIV replication because the viral RNA genome on its own is highly susceptible to degradation by intracellular RNases. RT rapidly makes a much more nuclease-resistant double-stranded DNA copy of the RNA template that later integrates to form the proviral DNA.
This molecule is used by retroviruses to create DNA by using mRNA as a template. We know that normally transcription is the synthesis of mRNA from DNA. This can be useful in bioengeneering when using a virus as a vector to alter the genetic material of the host.
A. If you have several samples of liquid and are told that one contains living organisms,
what type of in vestigation would you do to determine which liquid contains the living
things?
Answer: (Aerobic and anaerobic respiration)
Explanation:
Respiration by living organisms can be investigated by carrying out experiments to show the production of carbon dioxide and heat.
Investigating carbon dioxide production
Limewater turns milky in the presence of carbon dioxide. It can be used to show that exhaled air contains more carbon dioxide than inhaled air.
Carbon dioxide dissolves in water to form a weakly acidic solution. Hydrogencarbonate indicator is used to show the presence of carbon dioxide in solution. It is:
red at neutral pH (no carbon dioxide)
yellow at low pH (carbon dioxide present

HURRY PLEASE. Provides energy to an organism to conduct cellular processes A. water B. air C. food D. living space E. carbohydrates
Answer:
Carbohydrates
Explanation:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

d. 33%
Answer:
100%
Explanation:
Non-yellow mice in this situation seem to have both recessive genes for this trait.
Crossing these two mice with both recessive genes for non-yellow will result in 100% non-yellow offspring.

The average animal cell generally spends about 24 hours completing a cell cycle (18-20 hours of that being in interphase). The fastest dividing animal cell completes a cell cycle in about 9-10 hours. What would be some reasons for more rapid cell division
Answer:
The lack of Mad1 protein can cause faster cell division.
Explanation:
The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.
Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.
The cell cycle is the division of cells and the replication of the genetic material. The cell cycle requires 24 hours to complete the cell cycle, whereas some animals complete the cell cycle in 9-10 hours due to a lack of Mad1 proteins.
The correct answer is:
Lack of Mad1 proteins.
The function of Mad1 proteins are:
Mad 1 proteins regulate the attachment of chromosomes to the spindle microtubules. The proteins halt the cell cycle in the anaphase until the spindle apparatus is formed.The lack of protein in the other organisms causes rapid cell division. The protein is a checkpoint and arrests the cell cycle in anaphase, however, the lack of these proteins will cause a faster cell cycle.
Therefore, lack of Mad1 proteins will result in a faster division, because no checkpoint will be available in the anaphase of the cell cycle.

Example of form follows function in cell biology
Answer:
Example: human's arm and bat's wing share the same evolutionary origin and exhibit similar internal anatomical structures, but they have different forms because these structures have different functions
Explanation:
The idea "Form Follows Function" indicates that the form/shape of a structure is directly associated with the function of that structure. The relation form-function is a consequence of the evolutionary process. Thus, in different species, analogous structures that share the same evolutionary origin can have different forms and/or shapes because they perform distinct functions, such as in the example above.

A graph of KE vs the mass of an object is ___
Answer:
A non linear relationship
Explanation:
hope this helps.
A graph of KE vs the mass of an object is a non-linear relationship.
What are graphs?Graphs are the mathematical representations of numbers and data on graph paper. They are an easy way to see the changes in the data over time.
In nonlinear relationships, changes in any of the inputs are not proportionate to changes in the output. A nonlinear relationship produces a curve when it is plotted on a graph, whereas a linear relationship results in a straight line.
On a graph, kinetic energy has a linear relationship with respect to the mass of the moving object and a non-linear relationship with respect to how fast the object is moving.
Thus, the graph of KE will be a non-linear relationship.

2. What are individual characteristics? Give an example of an individual characteristic?
Answer:
What are individual characteristics? Give an example of an individual characteristic. Individual Characteristics are properties or physical evidence that can be attached to a common source, any examples could be something such as Nuclear DNA, tool marks, and fingerprints.
What are class characteristics and how are they different from an individual characteristic? Class characteristics are not unique to a particular object but place the particular bit of evidence into a group of objects. Individual characteristics narrow down the evidence to a single, individual source. The type of handgun with which a victim is shot is a class characteristic.
What are physical and chemical properties? Give an example of each. A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume. A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction. Examples of chemical properties are reactivity, flammability, and oxidation state.
What do forensic scientists do to collect and preserve soil samples? The combination of materials in soil may link a suspect to the crime scene if the soil is transferred to the suspects shoes or clothing. Forensic scientists compare soil samples to see if there is a match that links the suspect to the crime.
Explanation:
Individual characteristics are unique traits or attributes that distinguish one person from another.
These qualities are specific to an individual and may be influenced by genetics, environment, experiences, or personal choices.
Individual characteristics encompass a wide range of aspects, including physical features, personality traits, skills, interests, and preferences.
For instance, physical features such as eye color, height, or facial structure are individual characteristics that are genetically determined.
Personality traits like extroversion, empathy, or creativity are also individual characteristics shaped by a combination of genetic and environmental factors.
These characteristics contribute to the diversity and complexity of each person, making every individual special and different from others.
