Answer:
The correct answer is - 25% chances of having puppies with spotty fur.
Explanation:
In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:
Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive
Punnett square:
S s
S SS Ss
s Ss ss
By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.
What type of chemical bond exists between two water molecules
Hydrogen bonds, type of chemical bond exists between two water molecules.
What is a chemical bond?A chemical bond is what binds atoms in molecules together. Electrical forces between positive charge atomic nuclei and negative-charged electrons form bonds. A chemical bond is a long-lasting attraction between ions or atoms that allows molecules and crystals to form.
Hydrogen bonds arise between neighboring water molecules' hydrogen and oxygen atoms. A hydrogen bond is formed by the attraction of individual water molecules. A water molecule is made up of two hydrogen and oxygen atoms atom, with one partly positive hydrogen atom connected to a more highly electronegative atom.

Is race a biological characteristic determined by our genes?
Answer:
No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.

Answer:
thymine
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 protein stoichiometry ratio (base pair rule) of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
what is the difference between emphysema and chronic bronchitis? Thanks.
The main difference between these conditions is that chronic bronchitis produces a frequent cough with mucus. The main symptom of emphysema is shortness of breath. Emphysema can sometimes arise due to genetics. An inherited condition called alpha-1-antitrypsin deficiency can cause some cases of emphysema.

The organism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the daphnia environment, daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the daphnia allows the population to adapt to environmental change
Answer:
The characteristic of daphnia which allows the population to adapt to the environmental change is the short generation time.
Explanation:
As evident from the text, the maturity comes in 5 to 10 days and they reproduce for the next 2 months at a rate of 100 eggs every 3/4 days. This is a short generation time which makes the evolutionary changes easy and less time-consuming to incorporate.
A student was asked to prepare a model of the rock cycle as it moves matter slowly through the Earth. The student creates a model,
as shown here. In order to revise the model, how should the lettered components be modified in order to create an accurate model?
Select all choices that apply
es )
A)
Letter A should represent igneous rock that is extruded from magma,
B)
Letters A and B should both be igneous rock, which is found near the
Earth's surface.
C)
Letters and B should be sedimentary rock, which is found under layers of
other materials
D)
Letter C should represent metamorphic rock which changes composition
under heat and pressure.
E)
Letter B should represent sedimentary rock that is buried by layers of sand
and deposited material.
Answer:
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.
Explanation:
Igneous rock comes from magma/lava. Sedimentary rock is buried as layers are deposited. The metamorphic rock is formed when one type of rock changes from one form to another. The single letter options are all right here.
The Rock Cycle is related to transformation of three basic Rock types into one another through the Plate tectonic activity, along with weathering and erosional processes. Hence Correct options are A, D, and E.
The Rock CycleIt is a phenomenon through which three basic types of Rock transformed into one another. These three types of Rock are Igneous, Metamorphic, and Sedimentary rocks.
Therefore, to prepare a model which shows Rock Cycle, student need to have three types of Rock as mentioned in option A, D, and E.
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.

Ryder needs to determine the missing term in this set: sperm, egg, zygote, ________ Which term best completes the set?
Answer: fertilization
Explanation:
Answer:
Answer is D. Fertilization
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

Which of the following is a physical adaptation for the underlined animal?
Answer:
Physical adaptations do not develop during an individual animal's life, but over many generations. The shape of a bird's beak, the color of a mammal's fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals survive.
Una persona sana necesita 1500 cal diarias para mantener su peso y su actividad rítmica normal ¿Cuántos J se obtendrá en 18,5 horas?
Answer:
4838J se requieren en 18.5 horas
Explanation:
Para resolver esta pregunta debemos, primero, hallar la cantidad de calorías necesarias para 18.5h (Ya sabemos que para 24 horas se necesitan 1500 calorías). Después, este resultado debemos convertirlo a Joules (1cal = 4.184J):
Calorías en 18.5h
18.5h * (1500cal / 24h) = 1156.25cal son requeridas en 18.5 horas
Joules requeridos:
1156.25cal * (4.184J / 1cal) =

How are flowering plants and conifers alike? A.They both have incomplete flowers. bThey both make fruits. cThey both reproduce by means of seeds. dThey both have leaves that look like thin needles
Answer:
cThey both reproduce by means of seeds.
Explanation:
This is because both flowering plants and conifers reproduce by seeds. Although Conifers are gymnosperms, and angiosperms are flowering plants but conifers grow their seeds naked, it often appear on the scales of a cone, instead of encased in fruit. The flowering plants seeds are encased in fruits. Both conifers and flowering plants are vascular plants that is they have vascular tissues which help them conduct water and nutrients
