Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.

In moths, White wings are dominant to tan wings. If a Ww moth is crossed with a ww moth, what are the possible phenotypes for their offspring? (Draw a Punnett square to help you.)
0% White, 100% Tan
25% White, 75% Tan
50% White, 50% Tan
75% White, 25% Tan
100% White, 10% Tan
Answer:
The genotypes are: Ww,Ww,ww,ww
So we will have 50% White, 50% Tan
if you were to design an organism, what 3 organ systems would be the most important to include?
A female guinea pig that was pure-breeding for white fur, mated with a male guinea pig
that was pure-breeding for brown fur.
All the offspring had brown fur.
One of the male offspring mated with a female with white fur.
What proportion of white offspring would be expected from this cross?
one half
none
one third
O one quarter
Answer:
one half
Because they both were pure breed (bb and BB) and all the offspring came out as brown that means that brown is the dominant trait. So the offspring are all Bb and if the offspring mated with a white fur she would have to be bb meaning their children woild be either Bb or bb

Which part of the female reproductive system is highlighted below?
A. Ovary
B. Uterus
C. Cervix
D. Fallopian tube
Answer:
fallopian tube
Explanation:
The shown image is the uterus that is in option B, as the female uterus is a reproductive organ that is located in the lower part of the pelvic region and is also known as the womb. It is a pear-shaped muscular organ that is responsible for carrying a developing fetus during pregnancy.
What is a uterus?The uterus is made up of three layers of tissue: the endometrium, the myometrium, and the perimetrium. The endometrium is the innermost layer of the uterus, and it is the layer that thickens and sheds during the menstrual cycle. If a fertilized egg implants in the endometrium, pregnancy begins. The myometrium is the middle layer of the uterus and is made up of smooth muscle tissue. It is responsible for the contractions that occur during childbirth. The perimetrium is the outermost layer of the uterus and is made up of thin tissue that covers the uterus.
Hence, the shown image is the uterus that is in option B, as the female uterus is a reproductive organ that is located in the lower part of the pelvic region.

.Explicati de ce algele pluricelulare au culoarea rosie,verde respectiv bruna ?
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
Create a food chain that contains four organisms from a producer through three consumers using corn, rabbit, grass, wolf, snake, eagle, grasshopper, Fox, rat, and hawk.
Answer:
Corn → rat → hawk → wolf
Explanation:
A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.
Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:
Corn → rat → hawk → wolf
Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS

Select ALL of the following genotypes below that respresent males.
XXY
XX
XYY
XXX
XY
Answer:
Is it XXX that all males want?
Explanation:
Just joking! I still think it is XXY
The genotype that represents males is XY of 50 % of both X and Y chromosomes where a slight change in the alignment might cause to chromosomal disorders .
XXY , XYY , XY represents males genotypes.
What are chromosomal disorders ?
These are the disorders which are associated with the change in the normal XY sequence of males. Various disorders and syndromes are associated with the mutation and the responsible factor can be trisomy like.
XXY is a chromosomal mutation found in the males only called as Jacob syndrome, XYY is a chromosomal disorder called as klinefelter syndrome found in males only.
XX is the genotype of a female, XXX is a condition that affects 1 in every 1000 females.
Thus, except XX and XXX is the exception as both of these represent females.

Explanation:
Describe an adaptation to a plant's physical characteristic and explain how this adaptation helps the plant survive.
The development of stomata that are closed in arid conditions is an adaptation in plants. It allows plants to survive.
What is evolution?Evolution can be defined as descendence with modification, a process that involves natural selection.
Natural selection refers to the differential survival and reproduction of the more adapted organisms in a population.
Adaptations are specific features that allow organisms to have higher fitness in a population.
Stomata are structures for the interchange of gases (CO2 and O2) from the environment and can be closed to avoid water loss.

Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each. Use quotes appropriately; be sure your responses are written in your own words
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.

a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for
photosynthesis
c, the thermocline disappears in the winter
d. the upper and lower layers of water mix all year round
Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.
