Which phrase is an example of heterotrophic nutrition?
a. A deer eating grass in a field.
b. a tomato making its own food
Explain:
A.
All eukaryotes except for green plants are unable to manufacture their own food: They obtain food from other organisms. This mode of nutrition is also known as heterotrophic nutrition.
All heterotrophs (except blood and gut parasites) have to convert solid food into soluble compounds which are capable of being absorbed (digestion).Then the soluble products of digestion for the organism are being broken down for the release of energy (respiration). All heterotrophs depend on autotrophs for their nutrition. Heterotrophic organisms have only four types of nutrition.
Answer:
b a tomato making its own food

Which of the following molecules does NOT enter the cell via facilitated diffusion?
Fats
Nucleotides
Amino acids
Sugars
Monosaccharides
The molecule that does not enter the cell via facilitated diffusion is :
( A ) Fats
Facilitated diffusionFacilitated diffusion is a type of spontaneous transport system ( passive ) in which charged and polar molecules such as carbohydrates, Amino acids, Nucleotides and ions move across a biological membrane. with the aid of a specific transmembrane integral proteins while
Fats ( fatty acid ) enters the enterocyte through simple diffusion process via the plasma membrane.
Hence we can conclude that The molecule that does not enter the cell via facilitated diffusion is Fats.

A continuation of this will have what immediate impact on the local ecosystem?
Answer:
Understanding the status and trends of ecosystem services (ES) in a changing environment is important for identifying effective management measures of multifunctional mangrove ecosystems. Mangroves and their ES are jeopardized by a complex set of factors, with impacts that are experienced at local levels, especially in developing countries, where people often rely directly on natural capital for their livelihoods and well-being. This study was set to explore how local communities in the Rufiji Delta, situated in central coastal Tanzania, perceived the status and trends in mangrove ecosystem services (MES), associated drivers of change and the impacts of changes in MES on local livelihoods. A mixed methodological framework (including focus group discussions, key informant interviews, household surveys and direct observations) was used. People from villages close to mangroves rated the status of MES higher than those in villages distant from mangroves. Provisioning services (P) were often perceived to be in a worse and more declining state than regulating (R), cultural (C) and supporting services (S). A decrease in availability of poles and firewood (P), decline of fish habitats (S) and an increase in education value (C) were the most commonly perceived changes of MES in the study area. Illegal harvesting of mangrove poles, rice cultivation, climate change and inadequate management were seen as the most critical drivers of mangrove degradation, although the perceptions differed between sites. Rice farming was perceived to be a primary cause of mangrove loss by communities far from mangrove forests, while illegal exploitation was identified as the major driver by communities near mangroves. Fishing, collection of poles and honey were perceived as the most impacted livelihoods depending on MES. This together with the comparatively low status and declining trend of these MES indicate that they should be of high management priority as indicated by the first order management index used in this study.

In man, hitchhiker's thumb is domiant to a straight thumb, and brown eyes is dominat to blue eyes. If a man that has a straight thumb and brown eyes in the heterozygous form marries a woman that is heterozygous for hitchhiker's thumb and blue eyes, what is the chance that one of their children will have a straight thumb and blue eyes?
Answer:
25%
Explanation:
T = Hitchhiker's thumb
t = straight thumb
B = Brown eyes
b = blue eyes
The man's genotype is ttBb
The woman's genotype is Ttbb
Make a dihybrid punnett square to find the possible genotypes of the offspring
ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:
Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype
4 ÷ 16 = 0.25
0.25 × 100 = 25%
