In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.

Why are sex-linked disorders
more common in males?
A. Sex-linked disorders are more common in
females.
B. Males only need to inherit one copy of the
allele.
C. Sex-linked disorders are dominant.
Answer: B
Explanation:
Sex linked disorders are on the X chromosome and males have only 1
It is less common in females because they have 2 X chromosomes
Answer: B
Explanation: Men only have to inherit one copy of the disorder in order to have it since they’re XY and females are XX. With females, they could get another dominate trait to prevent them from having the disorder (they would then be a carrier) but with males there’s not any way to block it out.

7. If the diameter of the field of view when using the 4x objective is 3 mm, what is the area of the field of view when using the 4X, 10X, and 40X objectives
Answer:
Using 4X view =
1.767 x 4 = 7.068mm
Using 10X view
1.767 x 10 = 17.67mm
Using 40X view
1.767 x 40 = 70.68mm.
Explanation:
If the diameter when using 4x objective = 3mm
then the original diameter = 3/4 = 0.75 mm
The diameter of the field is 0.75 mm
Area of a circle = pie/4 x diameter square
pie = 22/7 or 3.14
diameter = 0.75
The area of the field
3.14 x 0.75 2 =
3.14 x 0.5625=
1.767mm.
The original area of the field = 1.767mm
Using 4X view =
1.767 x 4 = 7.068mm
Using 10X view
1.767 x 10 = 17.67mm
Using 40X view
1.767 x 40 = 70.68mm.
Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."

¿En cuál de los siguientes alimentos es posible encontrar una mayor cantidad de proteínas? A. Pera. B. Agua. C. Carne. D. Mantequilla.
Answer:
C. Carne
Explanation:
La proteínas representan un macronutriente (al igual que lípidos y carbohidratos) fundamental para el organismo. El consumo de proteínas es clave en la dieta porque el organismo utiliza estas moléculas (o sus bloques de construcción, los aminoácidos) para construir diferentes estructuras celulares y llevar a cabo diversos procesos vitales tales como, por ejemplo, reparar y desarrollar tejidos, funciones endócrinas, defender al organismo de agentes patógenos infecciosos, etc. En un adulto, la ingesta diaria de proteína debe rondar del 15 al 35% del total de las calorías consumidas al día, lo cual representa aproximadamente de 0.8 a 1.3 gramos por cada kilogramo de peso corporal. La carne es un alimento que aporta un gran contenido de proteínas y también es fuente de vitaminas y minerales (es decir, micronutrientes). Otros alimentos ricos en proteínas incluyen, por ejemplo, huevos, leche, legumbres (arvejas, garbanzos, lentejas) y la soja.

How is a spark from touching a doorknob the same as a bolt of lightning
Explanation:
That little spark you get when you touch the doorknob is essentially a miniature lightning bolt. When rain clouds move through the air, they build up positive and negative electric charges (Figure 7). So clouds have static electricity too! And when enough charge builds up, electric charges jump between the cloud and the ground.

-crocodile
ANATOMICAL FUNCTION-
-walking, and hopping
-swimming, walking/crawling
-flying, flapping wings
-using tools, picking up and holding objects
-swimming
-running, walking, jumping
Human - Using tools, picking up and holding objects
Whale - Swimming
Cat - Running, walking, jumping
Bat - Flying, flapping wings
Bird - Walking, and hopping
Crocodile - Swimming, walking/crawling
It was kind of confusing because both birds and bats fly and flap their wings, but birds also walk and hop, so this is correct

Enzymes catalyze chemical reactions in the human body. Which statement best describes how enzymes work?
A They speed up chemical reactions by increasing the activation energy.
B They slow down chemical reactions by increasing the activation energy.
C They speed up chemical reactions by lowering the activation energy.
D They slow down chemical reactions by lowering the activation energy.
Answer:
A
Explanation:
Hope this is helpful!!:)
Enzymes work by speeding up chemical reactions through the lowering of the activation energy of the reactants.
In every reaction, reactants need to summon a minimum energy amount before they can get to products. this energy is referred to as activation energy.
When an enzyme is introduced into a reaction, it lowers the activation energy. By doing so, reactants can get to products quicker because the mountain they need to climb has been lowered by the enzyme.
In other words, enzymes create a shorter route for reactants to take towards their destination - products.

1. Using what you have learned about Darwin's Evidence, which statement is true regarding the pictures above?
A. All organisms are of the same species
B. Fish embryos take a long time to develop because they change so dramatically as they develop.
C. Because the embryos all began to develop similarly, this could suggest that there was a common ancestor.
Answer:
I believe: C."Because the embryos all began to develop similarly, this could suggest a common ancestor." would be the best fitting of the current answer choices.
Explanation:
Process of elimination.
We know that organisms of the same species would all look essentially the same, and we know from the second image that they are nowhere near the same species.
Fish Embryos don't really have much to do with this overall, with the majority of the Embryos being from Mammals.
That leaves option C.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.
What is the relationship among the parts of this system?
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.

A short hike through the Sandia Mountains from early spring to late summer will often reveal several different species of penstemon. The Rocky Mountain penstemon blooms in the spring while the very similar inflated penstemon blooms in late summer. As a result, hybrids are rarely encountered.
Complete question:
Categorize the following situation as either a pre- or postzygotic isolating mechanism and then specify which type of pre- or postzygotic isolating mechanism it is.
A short hike through the Sandia Mountains from early spring to late summer will often reveal several different species of penstemon. The Rocky Mountain Penstemon blooms in the spring while the very similar inflated penstemon blooms in late summer. As a result, hybrids are rarely encountered.
Answer:
pre-zygotic isolating mechanismType: seasonal or temporalExplanation:
There are different mechanisms of reproductive isolation. These are barriers that inhibit or interrupt the genetic flux between different species. These mechanisms are about the biological characters of each species that prevent the reproduction with other species.
The reproductive isolation mechanisms might be either prezygotic or postzygotic.
Pre-copulatory or pre-zygotic: Ecological or due to habitat isolation; seasonal or temporal; Sexual or ethologic; Mechanical; Gamete incompatibility.2. Post-copulatory o post-zygotic:
Hybrid inviabilityHybrid sterilityHybrid with diminished viability and or fertilityCytoplasmatic interactions.The exposed situation is an example of prezygotic isolation due to seasonal or temporal barriers. Penstemon blooms in the spring, while the very similar inflated penstemon blooms in late summer. Probably, if they had the same reproductive season, they would produce hybrids. But as they are isolated by different reproductive seasons, they do not. As they can not even fertilize, they are considered to be prezygotic isolated species.
