It decreased in frequency over time.
Trait B decreased in frequency over time. So, the correct option is A.
What is trait?A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.
A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.
Hence, the correct option is A.

Beth wrote the following description of the life cycle of non-flowering, seed-bearing plants. Read her description and find the mistake.
"Non-flowering, seed-bearing plants go through four major stages in their life cycles. The first stage is when the plant is a seed from a cone. The second stage is when the plant sprouts out of the seed and the cones begin to grow. The third stage is when the plant is a seedling. The fourth stage is when the plant is a bigger seedling."
What statement corrects the error in Beth's report?
There are five stages in the life cycle of non-flowering, seed-bearing plants, not four.
The first stage is when roots will grow out of the seed and down into the soil.
The third stage is when the plant sprouts out of the seed and the flower grows.
The fourth stage is when the plant is an adult plant growing leaves and cones which produce more seeds.

matter 1. What do you think it means for a solid to have a definite shape? (hint: a gas/liquid does not have a definite shape). _________________________________________________________________________________________ 2. How can solids be transformed into other states of matter? Give an example. _______________________________________________________________________________
Answer:
1.) Particles in a solid have fixed locations in a volume that does not change. • Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
2.) It's a process called sublimation. The easiest example of sublimation might be dry ice. Dry ice is solid carbon dioxide. When you leave dry ice out in a room, it just turns into a gas.
The idea of GMO sounds really good. Why might someone be opposed to making healthier food that lasts longer or doesn't need pesticides?
Answer:
Explanation:
Genetically engineered foods are inherently unstable. Each genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.
Genetic engineering can also alter the nutritional value of food.
Another hidden risk of GE foods is that they could make disease-causing bacteria resistant to current antibiotics, resulting in a significant increase in the spread of infections and diseases in the human population.
Answer:
Many people believe that GMOs are bad for their health – even poisonous – and that they damage the environment.
Explanation:
Moreover, most GM crops are either bred to withstand chemical pesticides or developed to generate insecticides themselves. When herbicides are applied on resistant crops, the weeds acquire resistance over time, necessitating the use of even more chemicals. Crops genetically modified to generate pesticides, on the other hand, create poisons that are toxic not just to pests but also to other insects such as butterflies, moths, and insect pollinators.

Write a short paragraph to describe viscosity. Include at least two examples of fluids and the words “flow,” “fluid,” “particles,” and “viscosity.”
Answer:
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.
Explanation:
Answer:
Viscosity is the resistance of a fluid to flow (thickness or thinness of a fluid). Fluids with high viscosity do not flow as easy as fluids with a low viscosity. Temperature affects viscosity, the warmer the liquid, the faster the particles flow and the colder it is the slower it flows. For gases when temperature increases, less friction occurs so it the flow rate is higher and when its col the opposite thing happens

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins
Answer:
GR
Explanation:
the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings
The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.
When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.

- Click on the pen to write.
-Then click on the pen with the color line under it to change the color
of text.
-Circle the subscripts in blue
-Circle the coefficients in orange
Answer:
↓
Explanation:
I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.
Hopefully that makes sense! :)
