Fossils of ancestors of the modern horses show a small, 4-toed,
almost dog-like browsing animal named Eohippus. Over time, the
horses got larger, lost toes, and changed to a grazing diet. What is
the best explanation for why this change occurred?
Select one:
The horses needed to run faster, so they ran more and their leg
and foot structure adapted.
The horses changed their environment to fit their needs for
survival.
The horses with traits most suited to the changing environment
survived.
The horses took the extra energy from a grazing diet and used it
to grow larger.
Answers
An early version of the horse, known as Eohippus, had four toes and resembled a little dog. The horses grew bigger, lost toes, and switched to a grazing diet over time.
Can you lose weight through grazing?After all, eating small meals throughout the day helps to control your blood sugar levels and keeps you fed for your workouts. But according to recent research reported in the journal Cell Metabolism, grazing may be preventing you from losing weight, which is good for your health, especially if it lasts into the evening.
Do full meals or frequent snacking provide more energy?According to one study, grazing (which they examined with 6 meals per day) supported good glucose metabolism more than eating a diet with the recommended total caloric intake.

Suppose that phenotypic variation in the tail length of mice is summarized in the table below. 0.5 0.5 0.3 0.4 = 0.0 Additive genetic variance (VA) What is the narrow-sense heritability (h') of tail length? Dominance genetic variance (Vo) Genetic interaction variance (V) Environmental variance (VE Genetic-environmental interaction variance (VGE) Number What is the broad-sense heritability (H) of tail length? Number
Answers
phenotypic variation in the tail length of mice is additive genetic variance (VA) = 0.5, Dominance genetic variance (VD) =0.3, Genic interaction variance (VI) =0.1,Environmental variance (VE) = 0.4 and Genetic-environmental interaction variance (VGE) = 0.0. Narrow-sense heritability is 0.38. Broad-sense heritability is 0.38 and Broad-sense heritability is 0.69.
Narrow-sense heritability is VA/VP
= 0.5/1.3
= 0.38.
Broad-sense heritability is VG/VP
= (VA + VD + VI)/VP
= 0.9/1.3
= 0.69
The variance in phenotypes that exists in a population is known as phenotypic variation. People come in varied sizes and shapes, for instance; different phenotypes include differences in height, weight, and body form. The capacity to roll your tongue is a changeable trait, as are hair, eye colour, and skin tone.
Genotypic variation, or the variance in genotypes between people, is influenced by alleles. The genotype is the actual DNA code and is made up of the allelic makeup of a particular gene. Phenotypic variation, or the variation in phenotypes between individuals, can result from genetic variation.

Which of the following would cause cells to switch from cellular respiration to fermentation?
a. The final electron acceptor in the ETC is not available.
b. The proton-motive force runs down.
c. NADH and FADH supplies are low.
d. Pyruvate is not available.
Answers
The factor for cells switching from cellular respiration to fermentation is a) the final electron receptor in the TEC is not available.
The reason certain cells switch from respiration to fermentation is due to their oxygen supply and oxygen demand. If the oxygen demand of the cells is much higher than the oxygen supply, the cells can no longer sustain aerobic respiration. In this case, the cells switch from respiration to fermentation. Like combustion, cellular respiration completely oxidizes glucose to CO2 and water. Fermentation, on the other hand, does not completely oxidize glucose. Instead, small, reduced organic molecules are produced as a waste product. As a result, cellular respiration releases more energy from glucose than from fermentation.

3.0g of clean magnesium ribbon 8.0g of clean copper metal were burnt separately in equal volume of air and both metals reacted completely with air; a) State and explain where there was greater change in volume of air Mg =24 Cu = 64 (2 marks)
Answers
The copper metal is heated in the air. The magnesium ribbon emits a brilliant light with magnesium oxide, which is white. When oxygen gas is passed over copper in the presence of heat, an oxidation reaction occurs which results in the formation of black copper oxide. The greater change in mass observed when they start to burned.
What is copper metal ?Copper is a mineral and also an element which is essential to our daily lives. Copper is a significant industrial metal due to its high ductility, malleability, thermal and electrical conductivity, and corrosion resistance. Copper is a necessary nutrient in our diet.
Metals are a class of materials which have high light reflection. Copper (Cu), Aluminium (Al), and other metals are the examples.
The combustion of magnesium ribbon is a combined reaction. It is due to the fact that magnesium metal reacts with the oxygen to form the single product magnesium oxide. When magnesium ribbon is burned in the air, it reacts with the oxygen present in the air to form magnesium oxide.
Thus, 3g of clean magnesium ribbon and 8g of clean copper metal were burnt separately in equal volume of air and both mass reacted completely with air and the greater change in mass observed when they start to burned.

a) True
b) False"
Answers
Option b is Correct. Contrary to popular belief, an organism with IsCAP+P+O+Z+Y+A+/F'I+ will not have a healthy Lac operon.
The lac operon exhibits leaky expression, which ensures that even after the removal of lactose, a little amount of eiwit is still produced. When the requirements are violated, it is crucial to get the lactose metabolism going so that lactose cannot be broken down in the cel without permease.
When lactose is present, it binds to the repressor. Thus, the DNA is released by the repressor, allowing the operator to enter freely. RNA polymerase can now be sent via the operator to view the structural elements. Ribosomes are able to synthesize the essential enzymes in this place.

Answers
A living thing producing and emitting light is known as bioluminescence. Animals that glow in the dark can be found in all marine habitats, including those at the ocean's surface and on the deep seafloor.
What is bioluminescence?The production and emission of light by living things is known as bioluminescence. This type of chemiluminescence exists. Marine vertebrates and invertebrates frequently exhibit bioluminescence, as do some fungi, microorganisms, including some bioluminescent bacteria, and terrestrial arthropods like fireflies.
A chemical process that results in the production of light energy inside an organism's body causes bioluminescence. A species must contain luciferin, a molecule that creates light when it reacts with oxygen, in order for a reaction to take place.
Utilizing specialized cameras with extremely sensitive detection systems, the bioluminescence emitted can be detected and boosted.

The miRNAs in a cell inhibit protein synthesis by forming complementary bonds with mRNA True Or False
Answers
True. MicroRNAs (miRNAs) are small non-coding RNAs that play an important role in gene regulation.
They are produced from longer non-coding RNA transcripts and then bind to complementary sequences on mRNA molecules, typically in the 3' untranslated region (3'UTR). By binding to the mRNA, miRNA inhibits its translation into a protein, thus repressing the expression of the gene encoded by the mRNA. This type of regulation is known as post-transcriptional gene regulation.
miRNA have been shown to be involved in a wide range of cell processes, such as development, differentiation, proliferation, and apoptosis.

A. The hypothalamus sends the needed hormone to the body.
B. The hypothalamus sends a messenger hormone to the pituitary gland.
C. The hypothalamus determines which area of the brain it activates.
Explanation:
What is the Hypothalamus?The hypothalamus, which is a structure deep within the brain, serves as the body's intelligent control and coordination center. Its primary duty is to maintain the body in a steady state known as homeostasis. It accomplishes this by either directly altering the autonomic nervous system or controlling hormones.
Answer BreakdownChoice A is the best answer. The hypothalamus is the gland in the body that is responsible for homeostasis. Therefore, the hypothalamus will produce the necessary hormone the body needs to retain homeostasis.Choice B is not the best answer. Depending on the body's exact response, the hypothalamus may send a messenger hormone to the pituitary gland. However, the hypothalamus is generally responsible.Choice C is incorrect. The hypothalamus can transmit hormones that may go to the brain or interact with neurotransmitters in the brain but it does not "activate a portion of the brain" to maintain homeostasis.
