Answer:
The correct answer is : surveying.
Explanation:
Paleo-anthropology is the study of the extinct primates, it is a sub branch of anthropology. It is focused on the human evolution and rise of the sub type of family of the other human or hominids.
Surveying is the one of paleoanthropoolgy practices that involves the finding the fossils of hominids on the surface of all around the globe by walking to compare it and study the evolution of human family.
Thus, the correct answer is- surveying.
The specification of the anterior-posterior axis in Drosophila embryos is initially controlled by various gene products that are synthesized and stored in the mature egg following oogenesis. Mutations in these genes result in abnormalities of the axis during embryogenesis. These mutations illustrate maternal effect. What are the expected outcomes of parallel crosses involiving mutant gnes that contrast maternal effect and organelle heredity?
Answer:
It is possible to determine their functions and to identify the mechanism involved in their mode of inheritance
Explanation:
Matrilineal inheritance refers to the inheritance of genes directly from the mother, it either through the inheritance of mitochondrial DNA or by the epigenetic mechanism of genomic imprinting (in the case above indicated, maternal imprinting). By mutating genes which are inherited from the mother it is possible to study their functions as well as their mode of inheritance. By using a reverse genetics approach, many maternal imprinted genes have recently been identified to be involved in embryo development, especially in model organisms like Drosophila.
You have learned that humans have a total of 46 chromosomes and that chimpanzees have a total of 48 chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you? What did your research suggest about the relationship between chromosome number and organism complexity?
Answer:
The correct answer is included in the Explanation section
Explanation:
An organism with considerable more chromosomes than humans: the plant Ophioglossum reticulatum with 1260 chromosomes.
An organism with considerable fewer chromosomes than humans: the ant Myrmecia pilosula with 1 chromosome.
It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.

Explanation:
Research Problem: You come across three new species of primates that all cohabitate the same forested area. No one has looked at the behavior of these monkeys before so there is lot to discover about each species. You and a fellow researcher are interested in describing the diet of each of these species (Do they eat fruits? Leaves? Insects? Tree-sap? A combination of sorts?). Your fellow researcher has determined that her hypothesis is that two of the monkeys primarily eat fruit, while one of the monkey species eats tree sap.
Answer:
there are three different species.
Explanation:
There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.

What compound is this?
Carbohydrates
Lipids
Nucleic acids
Proteins
Answer:
Nucleic acids.
Explanation:
Extremely helpful Bio mnemonics to remember are:
Carbohydrates & Lipids - CHO
Proteins - CHON
Nucleic acids - CHONP
Because of the "CHONP" mnemonic, I was immediately able to recognize the compound as a nucleic acid after seeing the "P", which represents phosphorous.
Carbohydrates, lipids, nor proteins will include "P"; only nucleic acids.
The wild-type eye color in the fruit fly Drosophila melanogaster is dark red, as a result of a mixture of bright red and brown pigments. "Enzyme A" is encoded by the "a" gene, and is required to synthesize the bright red pigment. A lack of red pigment results in a somewhat brown eye color. You cross two fruit flies who are heterozygous for a recessive mutation that completely inactivates the "a" gene. What proportion of their offspring will have a recessive eye color phenotype?
Answer:
1/4 or 25%
Explanation:
Let the wild-type eye color be represented by allele A. The mutant's eye color would be represented by allele a.
The genotype of fruit flies that are heterozygous for a recessive mutation that inactivates gene 'a' ( and therefore results in mutant eye color) would be Aa.
If Aa and Aa are crossed:
Aa x Aa
progeny: AA Aa Aa aa
The proportion of the offspring that will have a recessive eye color phenotype (aa) would therefore be 1/4 or 25%.

which combination of the state and a substance in that state is correct
Answer:
Change of state of matter: In physics, we call the process of changing matter from one state to another state as change of state of matter. They can be transformed into each other, so there are 6 kinds of physical changes: melting, solidification, vaporization, liquefaction, sublimation, and sublimation. Other states of matter such as: plasma state, super solid state, neutron state, Bose-Einstein condensed state, soft matter, etc.
Explanation:
1. State of matter: Since a large number of molecules that make up a substance are constantly performing irregular thermal motion, and different molecules perform thermal motion at different speeds, three states of matter are formed: solid, liquid, and gaseous. In science, we call the state of matter the state of matter.
2. How to judge what kind of state change is happening: The key is to find the two states of the substance before and after the change in state, and then compare them according to the definition, and then you can draw the correct conclusion.
Three states, six changes and endothermic hveat release: Physical change
Melting: solid → liquid (endothermic)
Solidification: liquid→solid (exothermic)
Vaporization: (boiling and evaporation): liquid → gas (endothermic)
Liquefaction: (two methods: compressing volume and lowering temperature): gas → liquid (exothermic) Sublimation: solid → gas (endothermic)
Sublimation: gas state → solid state (exothermic)
(Note: The "heat" of "endothermic" and "exothermic" mentioned here refers to heat, not to thermodynamic concepts such as temperature, internal energy, calorific value, and specific heat capacity. That is, "absorbed heat" and The abbreviation for "release of heat." In physics, heat cannot say "how much heat it contains" or "how much heat it has", but can only say "how much heat is absorbed" or "how much heat is released")

Gastrin secretion in response to elevated ph within the stomach is an example of:__________.
Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.
Coloration in mockingjays is determined by a single gene. The G allele leads to grey colored feathers and the g allele leads to all white feathers. If two heterozygotes are crossed, what would be the phenotypic ratio in the F1 progeny? What would be the genotypic ratio in the F1 progeny
Answer:
F1 genotype = 1: 2: 1
F1 phenotype = 3:1
Explanation:
given data
G = allete for grey colour feather
and
g = allele for white colour fether
and
Gg = genotype of heterozygotes
we do here cross of two heterozygotes that is
parantal generation Gg × Gg
⊥ ⊥
G g G g
gametes ⇒ F1 generation
F1 genotype = 1: 2: 1
F1 phenotype = 3:1

2. Ivan and Braxton want to know if a stretching a rubber band at different lengths affects how far the rubber band will fly. They will use centimeters for all measurements. IV: DV: Hypothesis: 3. Will a paper airplane with longer wings fly farther than shorter wings?
Answer:
Independent variable: DIFFERENT LENGTHS OF STRETCHING
Dependent variable: DISTANCE RUBBER BAND FLIES
Hypothesis: IF a rubber band is stretched longer, THEN the distance it flies will increase
Explanation:
The hypothesis of an experiment is a testable explanation or suggested solution to an observed problem or asked question. In this experiment, the hypothesis can be: IF a rubber band is stretched longer, THEN the distance it flies will increase
Note that, this hypothesis can be tested to be true/untrue
Independent variable is the variable that the experimenter manipulates or changes in order to bring about a response. The independent variable in this question is DIFFERENT LENGTHS OF STRETCHING THE BAND.
Dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, the measured/dependent variable is the DISTANCE RUBBER BAND FLIES

Jason wanted to find out how he could increase the number of popcorn kernels that pop when cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed 100 kernels of “Pop Rite’ popcorn into a popcorn popper that contained different amounts of oil. He used the following amounts of oil: 5 mL, 10 mL, 15 mL, 20 mL, and 25 mL He conducted the test 3 times for each amount of oil. He then counted the number of kernels that had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.
Answer:
This question is incomplete, it is asking to identify the following variables in the question:
Independent Variable: DIFFERENT AMOUNTS OF OIL
Dependent Variables: NUMBER OF KERNELS THAT POPPED
Controlled Variables: TIME FOR POPPING, SAME BRAND OF KERNEL, SAME COOKING TIME
Explanation:
The independent variable of an experiment refers to the variable that the experimenter intentionally manipulates or changes for the purpose of effecting a measurable response in another variable (dependent variable). In this experiment, the independent variable is DIFFERENT AMOUNTS OF OIL used because this is what Jason changes in the experiment.
Contrarily, the dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, Jason measures the NUMBER OF KERNELS THAT POPPED from using different amounts of oil. Hence, the NUMBER OF KERNELS THAT POPPED is the dependent variable.
Controlled variables or constants are those variables that must be kept constant or unchanged throughout the experiment in order not to influence the findings of the experiment. In this case, the following variables were kept constant for all the groups: TIME FOR POPPING , SAME BRAND OF KERNEL (Pop rite), SAME COOKING TIME (4 mins).

Select one:
Answer:
fragilitas crinium
Explanation:
It is a condition in which the hair of the head or face tends to split or break off.
Small cracks started in the cuticle and splitting the hair entirely is known as brittle hair, fragilitis crinium, or Trichoptilosis.
What is the technical name for brittle hair?The technical name for brittle hair is known as fragilitas crinium. The condition may be triggered by things such as blow-drying, ironing the hair, over-brushing, perming, or excessive chemical use.
In some cases, trichorrhexis nodosa is caused by an underlying disorder, including very rare ones, such as Thyroid not making enough thyroid hormone (hypothyroidism).
The cuticle is the clear outside covering of the hair shaft. It is made up of tough, overlapping scales, like those on a fish or like shingles. A splitting of the hair shaft, usually at the distal end. Probably the most common of hair shaft disorders often referred to as 'split ends'.
Therefore, small cracks started in the cuticle, and splitting the hair entirely is known as brittle hair, fragilitis crinium, or Trichoptilosis.
