Which best describes the role of communication in scientific investigations?
Communication can help identify good scientific questions to further investigate.
Communication is not necessary once the data are collected because the scientists can do the data analysis
themselves.
Communication should not be used in planning the experimental design because the scientists want to have
original ideas.
Communication is important because the scientists need to convince other researchers not to challenge their
results.
Answer:
The correct answer to the following question will be Option A (Communication may allow us to identify great research problems for further study).
Explanation:
Research thrives as researchers interact more successfully. Becoming able to articulate the importance and effect of research thoughts as well as findings will enhance the effectiveness of researchers to obtain funding or find a job.It helps them could write and therefore more intelligible research articles.The other given choices are not related to the given situations.

Darwin observed fossils of glyptodonts, which are now extinct. Living armadillos are the only animals remaining on Earth that are similar to glyptodonts. Armadillos live in the same places that glyptodonts lived. What did Darwin most likely conclude about the two types of animals? Glyptodonts were better adapted to the environment. Glyptodonts outcompeted armadillos for food. Glyptodonts were early relatives of armadillos. Glyptodonts had the exact same adaptations as armadillos.
Answer:
3. Glyptodons were early relatives of armadillos.
Explanation:
Darwin would have come to this conclusion because glyptodons over time became armadillos, which you can tell by evolution that they were better evolved to survive than glyptodons. Due to this, they outlived the glyptodons.
Hope this helps! =)
Answer:
C
Explanation:
Over time glyptodonts became armadillos due to evolution
A heterozygous organism has
1.three different alleles for a trait
2. Two identical alleles for a trait
3. Only one allele for a trait
4. Two different alleles for a trait
I'm completely sure your answer would be D.
It has two different alleles for a trait!
An organism that is heterozygous has two different alleles for the same trait. Therefore, the correct option is B.
Alleles are genetic variants that affect the way a trait is expressed in different ways. During sexual reproduction an organism receives one allele from each parent. If these alleles disagree, the organism is said to be heterozygous for that trait. Two different alleles enable genetic diversity and the possibility of different phenotypic outcomes. A dominant allele may be expressed as a result of heterozygosity, while the effect of a recessive allele may be obscured. This genetic diversity is important for evolution because it gives rise to natural selection and the ability to adapt to changing conditions.
Therefore, the correct option is B.

The term that describes placing the thumb of one hand inside the mouth and the index and third finger of the other hand outside the mouth, and gently feeling the tissues for any lumps or abnormalities is:
Answer: PALPATION.
Explanation: Palpation is one of the the ways of physically examining an individual,it involves using one's fingers to examine the organs of the body to note any abnormality.
This is achieved by touching and feeling the the body inorder to determine the location,size,consistency or firmness, shape, tenderness and the texture of a body organ or to get the location of pain.
Palpation is mainly employed in physical examination of the abdomen and it can serve as a diagnostic approach to ascertain the presence of a disease condition or injury.
Palpation can be deep palpation (4-5cm) to feel internal organs of the body and to note any mass or tumour or light palpation(1-2cm) to feel surface abnormalities.
Answer:
palpation
Explanation:
The correct answer would be palpation.
Palpation is a medical term that generally refers to the process of using fingers to diagnose diseases or identify body abnormalities.
By using the sense of touch, different characteristics of the body region are assessed and the information is collated and critically examined to arrive at a diagnosis.
Palpation can be conducted using the fingertips, the finger and the thumb, the back of the finger and the hands, the side of the hands, or the front of the fingers

A neuromuscular junction is a junction between a_________ and a ___________. A neuromuscular junction is a junction between a_________ and a ___________. dendrite of an axon; skeletal muscle fiber bulbous end of axon; skeletal muscle fiber sarcoplasm; T-tubule dendrite of an axon; myofibril bulbous end of axon; cell body of axon
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.

This lab activity is designed to explore the effect of two substances on the heart rate of a Daphnia magna specimen. One of the activities in this lab is to measure the heart rate when the Daphnia is exposed to alcohol. In the experimental setup, what would be the independent variable?
Answer is given below
Explanation:
Heart rate was studied in this experiment and is the dependent variable studied or measured. This is a dependent variable. An independent variable is a variable whose modulation is not affected by any other variable in the experiment. Here is the alcohol independent variable. Other substances such as intelligence are also independent variables.Which example is a long-term environmental change?
La Niña
El Niño
climate change
small asteroid impact
Answer:
The correct answer would be Climate Change.
Profesional Explanation:
La Niña is incorrect because it is the cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns, which is not a long-term environmental change. El Niño is incorrect because it is an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, which is also not a long-term environmental change. A Small asteroid impact is incorrect because it will happen so suddenly, which is not a long-term environmental change. Climate Change is correct because it will keep changing over time causing a long-term environmental change.
Climate change is a long-term environmental change. Thus, the correct option is C.
What is Climate Change?Climate change may be defined as the process of long-term alterations in the climate or weather pattern of a particular place.
La Nina, El Nino, and small asteroid impacts occurred suddenly with the cause of only small-term effects.
La Lina is associated with the cooling down of water in a given region, El Nino effects lead to the rise of the average earth's temperature.
Therefore, Climate change is a long-term environmental change. Thus, the correct option is C.

What might be the correlation between the clarity of the lake water and the occurrence of the full body plate trait? What might you conclude about the clarity of the water from 1950 to 1980 based on this correlation?
Answer:
The clarity of the lake water isn’t specified so assuming the clarity improved and other predatorial fish were able to target stickleback fish more easily the full body plating had to come into play to make it more difficult for them to be preyed upon and to give them a better chance at escape.
Explanation:
The clarity of the lake water though not specified in this context. The full
body plate will help the stickleback fish to escape from its predators.
Water clarity is defined as the amount of light which is able to penetrate into
water bodies thereby making it easier for animals in it to see and hunt
properly for their food.
The improvement in water clarity will give the predatorial fish an advantage
to easily hunt stickleback fish. The full body plate trait will therefore give it a
form of adaptation to enable ity escape from other predators in the water
body.
