How are increased CO2 levels and increased temperatures affecting plant growth in the two experiments shown?
High CO2 levels cause plants to thicken their leave ,which could worsen climate change effect researchers says.
plant scientists observed that when CO2 levels increase in the atmosphere most plants do unusual , they thicker their leave
germination increase in high temperature up to the point
Increased CO2 levels and temperatures affect plant growth by bringing about a corresponding increase.

How does actin and myosin work together to help you lift an object?
Answer:
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.
Actin and myosin work together to help you lift an object in the following way:
Muscles are tissues of the musculoskeletal system that have the function of generating a force towards the bones with the ultimate goal of performing a movement.In order for this function to be carried out correctly, it needs proteins that are found inside the muscle fiber, these proteins are myosin and actin.The myosin head in the presence of ATP binds with the actin filaments, in order to generate a minimum slip that later becomes a coordinated and precise movement as lift an object.That is, myosin binds to the actin protein to generate the contraction of the muscles, and therefore the movements we make with our extremities.Therefore, we can conclude that actin is a cellular protein in muscles that is involved in muscle contraction when it connects with myosin.

A. Plants use carbon dioxide in the atmosphere during photosynthesis, herbivores eat the plants, and a carnivore eats an herbivore.
B. Carnivores use carbon dioxide in the atmosphere during cellular respiration.
C. Herbivores use carbon dioxide during photosynthesis, and a carnivore eats an herbivore.
D. Plants use carbon dioxide in the atmosphere during photosynthesis, and a carnivore eats the plants.
Plants use carbon dioxide in the atmosphere during photosynthesis, herbivores eat the plants, and a carnivore eats an herbivore.
How carbon move from atmosphere to the biosphere?Carbondioxide gas move from atmosphere to the biosphere by absorbing by the plants in the process of photosynthesis. These plants are the food of herbivores so they eat it and carbon move from plant to herbivore. Then the carnivore feed on the herbivore.

Según la historia evolutiva y sus diferentes saltos, ¿Qué linaje de especies es más antiguo?
A-Reptiles
B-Peces
C-Anfibios
D-Aves
es la A
Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.

Answer:
The correct answer is 4. Plateaus.
Explanation:
A plateau is a relatively flat, relatively high-lying part of the earth's surface that is wholly or almost wholly bounded by steeply sloping terrains. There is a pronounced slope on at least one side. The original flat area has mostly risen vertically as a whole due to geological factors. It may possibly have been cut by rivers, giving the impression of a hill or mountain landscape, but this is not it.

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
Answer:
the signals have different frequency
Explanation:
The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.
Answer:
D.anywhere its service broadcasts and it can receive a signal.

One end of the rope is vibrated to produce a wave with a wavelength of 0.25 m. The
Frequency of the wave is 3.0 Hz. What is the speed of the wave? *
1)3.00m/s
2)2.50m/s
3)0.75m/s
4)1.25m/s
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
On a warm day near the ocean, a breeze or wind often blows from the water to the land. Explain why this happens
Answer:
It occurs because of the difference in temperature between the ocean and the land.
This happens because the land heats up faster than the water, causing the air to rise above the land and allowing cooler air from the ocean to move in and take its place.
What is sea breeze?Because land and water have different capacities for holding heat, the land will heat up more quickly than the water on a hot day near the ocean. As a direct consequence of this, the air that floats above land tends to become warmer and less dense than the air that floats above water. Because of this, a region of low pressure is created over the land, while a region of high pressure is created over the water. In order to maintain a natural equilibrium, air will always move from areas of higher pressure to areas of lower pressure.
A breeze or wind that blows from the water to the land is caused by the air that is cooler and denser over the water moving towards the air that is warmer and less dense over the land. This phenomenon, which is referred to as a sea breeze, can assist in moderating temperatures on land, thereby making it feel more bearable and pleasant to be there.

You are replicating Gregor Mendel's famous experiment with sweet peas. The genotype for dominant smooth-seeded parent is designated AA, while the genotype for the wrinkled-seeded parent is aa. Using a punnet square predict the first generation for this cross. What are the genotypic and phenotypic ratios? SHOW ALL WORK.
Answer:
The correct answer is -
A. genotype ration = 1/1 or 100% of Aa.
B. phenotype = all smooth-seeded.
Explanation:
According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA
gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.
Punnett square:
A A
a Aa Aa
a Aa Aa
In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.
And phenotypically 100% chances of the smooth seed plants.

The early ancestors of horses showed the presence of digits on their limbs, while modern horses have hooves. What are likely possible reasons for this change?
Answer:
Natural Selection & Fitness
Explanation:
Horses have evolved to run as fast as possible because they are prey animals.
The hooves give advantages to the predecessors to the modern horse rather than the foot-bearing horses.
Thus when somebody inevitably becomes a snack, the hoof bearing horses lived longer. (Natural selection)
Because they've lived longer, they've had more babies. (Fitness)
Their babies are more likely to pass on the genes they've inherited from their successful parents, and the population of hooved-horses begins to exceed the population of footed-horses.
In this circumstance, all the footed-horses are gone. The population has evolved.
