How many chromosomes are in the cells after they divide? How many chromatids are there?
Answer:
two chromatids
After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids). As a cell prepares to divide, it must make a copy of each of its chromosomes.

The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of answer choices choanoflagellates are animals choanoflagellates are more closely related to sponges than they are to protists choanoflagellates and sponges evolved similar cell structures through convergent evolution choanoflagellates and sponges are sister groups
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
Why do birds migrate south during the winter?
A. strong northern winds drive them south
O B. an increase in predators drives them south
O C. to find food
O D. to find better nest building materials
Answer:
C. to find food.
Explanation:
It is hard to find food in the winter for animals besides humans. So they need to head south for warmer climates.
a. Draw a food chain that could exist in your ecosystem.
b. Draw a large arrow to show how the energy flows through your food chain
Answer:
Explanation:
This is an example
A. The following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
B. The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
Food Chain:
Consider the following food chain in a simple terrestrial ecosystem:
Grass → Grasshopper → Frog → Snake → Hawk
In this food chain, the grasshopper is the major producer, the frog is the secondary consumer, the snake is the tertiary consumer, and the hawk is the quaternary consumer.
B. Flow of Energy:
The giant arrow representing the flow of energy through the food chain would start with grasses and progress through each trophic level. Energy moves along the food chain in a way that passes from one organism to another when it is consumed.
The energy flow will be directed as follows:
grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)
The arrows indicate that the sun's energy is taken up by the grass through photosynthesis and then transferred to each successive level when the organism consumes it.

explain how the genus and species name of an organism is properly written
Answer: The binomial system of nomenclature is structured so that the scientific name of a plant consists of two names: (1) the genus or generic name, and (2) the specific epithet or species name. ... The genus name is always underlined or italicized. The first letter of the genus name is always capitalized.
Explanation:
a recipe calls for 1 cup of sugar and 1/2 cup of flour.Zoe uses 1 cup of salt and 1/2 cup of flour.
which kind of mutation is best modeled by zoes version of the recipe
Answer:
Substitution
Explanation:
Given the information in the question substitution seems like the most appropriate answer. Zoe used 1 cup of slat rather than 1 cup of sugar, she substituted sugar for salt.
Insertion is wrong because Zoe did not add another ingredient, there is still only 2 ingredients.
Transition is wrong because, given the information, because the state(liquid or solid) of the ingredients has not changed. Zoe is still use dry ingredients per say.
And beneficial also seems to be wrong because we don't know if using salt instead was beneficial to the recipe or to Zoe.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
